iPhone Apps Crashing or Not Opening After iOS 26.7 Update

After installing iOS 26.7, some iPhone users may notice that certain apps suddenly crash, freeze on the loading screen, close immediately after opening, or refuse to launch at all. In other cases, an app might work for a few seconds before returning to the Home Screen.

Apple released iOS 26.7 on September 14, 2026, with new features, bug fixes, and important security updates. Although updating your iPhone is recommended, major system changes can sometimes expose compatibility problems in apps, cached data, permissions, networking configurations, or app components that have not yet been optimized for the latest iOS release.

If your iPhone apps are crashing or not opening after the iOS 26.7 update, work through the troubleshooting methods below. Start with the simpler fixes before deleting apps or resetting settings.

Why Are Apps Crashing After the iOS 26.7 Update?

An app crashing immediately after an iOS update does not necessarily mean that iOS 26.7 itself is broken. The update can change system frameworks, security behavior, memory management, permissions, and background processes that apps depend on.

Common causes include:

• The app has not yet been optimized for iOS 26.7.
• An outdated version of the app is installed.
• Temporary app data became corrupted during the update.
• Your iPhone has very little available storage.
• A background iOS process has become stuck after installation.
• A VPN, DNS service, ad blocker, or network configuration is preventing the app from connecting.
• The app’s servers are temporarily unavailable.
• Permissions or system settings changed after the update.
• The app has a bug that requires an update from its developer.

If several completely unrelated apps are crashing, the problem is more likely connected to iOS, storage, memory, or system settings. If only one app is affected, the problem is more likely related to that particular app.

1. Force Close and Reopen the Crashing App

Start by completely closing the affected app. This removes its active session from memory and forces iOS to create a fresh process when you open it again.

On an iPhone with Face ID:

• Swipe up from the bottom of the screen and pause in the middle.
• Find the app that is crashing.
• Swipe its preview upward to close it.
• Wait a few seconds and reopen the app.

Do not repeatedly force close every app on your iPhone. iOS manages background apps automatically, so this should mainly be used when an app is frozen or behaving incorrectly.

2. Restart Your iPhone After Installing iOS 26.7

A restart is one of the most effective fixes when apps start crashing immediately after an iOS update. Although the iPhone restarts during installation, another restart can clear temporary processes that became stuck while iOS was completing post-update tasks.

Press and hold the Side button and either Volume button until the power slider appears. Drag the slider, wait about 30 seconds, and turn the iPhone back on.

After restarting, open the affected app before launching several other apps and check whether the problem continues.

3. Update All Apps From the App Store

This is particularly important after installing iOS 26.7. Developers frequently release compatibility updates around major iOS releases to address crashes, interface problems, authentication errors, and changes to Apple frameworks.

Open the App Store, tap your profile picture, open the available app updates section, and install all pending updates.

If the crashing app has an update available, install it first and test the app again. An app built for an older iOS environment may launch normally on the previous version but encounter problems after an operating system update.

4. Check Your Available iPhone Storage

Low storage can cause surprisingly strange problems after an iOS update, including slow performance, failed downloads, apps freezing, and apps unexpectedly closing.

Go to:

Settings > General > iPhone Storage

Check how much free space remains. If your storage is nearly full, remove unnecessary downloads, large videos, offline streaming content, old attachments, or apps you no longer use.

Try to maintain several gigabytes of free storage where possible. Apps often need temporary storage for databases, caches, downloads, updates, and normal operation.

5. Force Restart Your iPhone

If a normal restart did not help, try a force restart. This is especially useful if apps are freezing along with other parts of iOS.

For modern iPhones:

• Quickly press and release Volume Up.
• Quickly press and release Volume Down.
• Press and hold the Side button.
• Keep holding it until the Apple logo appears.

A force restart does not delete your photos, apps, or personal files.

6. Check Whether the App Requires Internet Access

An app that remains stuck on its logo or closes while loading may actually be experiencing a connection problem rather than a traditional crash.

Switch between Wi-Fi and mobile data and try opening the app again. You should also temporarily disable any VPN, custom DNS service, firewall, content filter, or network-level ad blocker.

Banking apps, streaming services, games, social networks, and work apps can behave incorrectly when they cannot contact authentication or configuration servers.

7. Check Cellular Data Permission for the App

If an app works on Wi-Fi but fails when using mobile data, check whether cellular access is allowed.

Open Settings > Cellular and find the affected app. Make sure cellular data access is enabled.

You should also check the app’s section under Settings > Apps for permissions it requires, such as Photos, Bluetooth, Local Network, Camera, Microphone, or Location.

8. Offload the App and Reinstall It

Before deleting an app completely, try offloading it. Offloading removes the application itself while retaining its documents and data.

Go to:

Settings > General > iPhone Storage > Select the App > Offload App

Afterward, tap Reinstall App.

This replaces the installed application files and can fix corrupted components without immediately removing locally stored app data.

9. Delete and Reinstall the App

If offloading does not work, a complete reinstall may be necessary.

Before deleting the app, make sure important information is synchronized with iCloud, the app’s account, or another backup service. Some apps store information only locally, and deleting them can permanently remove that data.

Once you have confirmed your data is safe, delete the affected app, restart the iPhone, and download a fresh copy from the App Store.

This is particularly effective when only one app started crashing after the iOS 26.7 update.

10. Check for Another iOS Update

Open:

Settings > General > Software Update

If Apple has released a newer version than iOS 26.7, install it. Apple sometimes releases follow-up updates when problems affecting system stability, security, or compatibility are discovered after a wider rollout.

Avoid installing beta versions simply to fix an app crash unless you intentionally participate in Apple’s beta software program. Beta releases can introduce additional problems.

11. Find Out Whether the App’s Servers Are Down

If an app opens but crashes or freezes during login, loading, payment, or synchronization, check whether the service itself is experiencing an outage.

Try accessing the company’s website or checking its official status page or support account. If many users are experiencing the same issue, repeatedly reinstalling the app will probably not solve anything.

In that situation, the app developer or service provider needs to fix the server-side problem.

12. Reset All Settings

If multiple apps continue crashing after iOS 26.7 and the previous solutions have failed, resetting system settings can help eliminate corrupted configurations.

Go to:

Settings > General > Transfer or Reset iPhone > Reset > Reset All Settings

This does not erase your photos, messages, documents, or installed apps. However, system preferences are restored to their defaults, including saved Wi-Fi networks, privacy settings, Bluetooth pairings, VPN configurations, Apple Pay cards, notification preferences, and several other settings.

Because of that, use this method only after trying the simpler solutions.

How to Tell Whether iOS 26.7 or the App Is Causing the Crash

Only One App Is Crashing

The app itself is the more likely cause. Update it, offload it, reinstall it, and check whether the developer has acknowledged compatibility problems with iOS 26.7.

Several Apps Are Crashing

If apps from different developers are closing unexpectedly, restart the iPhone, check available storage, install pending app updates, and check for a newer iOS release.

Apple Apps Are Also Crashing

If apps such as Safari, Messages, Photos, Settings, or other built-in Apple apps are also repeatedly crashing, the problem may be at the system level. A force restart and subsequent iOS update should be prioritized.

Additional Tips to Prevent Apps From Crashing

• Keep both iOS and your apps updated.
• Avoid keeping your iPhone storage completely full.
• Restart the device if unusual behavior begins after an update.
• Remove outdated VPN or network-management profiles you no longer use.
• Avoid beta versions of apps and iOS on your primary phone unless necessary.
• Back up important app data before reinstalling applications.

Frequently Asked Questions

Why are my apps crashing after updating to iOS 26.7?

The most common reasons include outdated apps, temporary system problems, corrupted application files, low storage, network issues, or compatibility bugs introduced by changes in the new iOS version.

Will deleting an app fix crashing on iOS 26.7?

It can. Reinstalling replaces the app’s files and clears corrupted local components. However, deleting an app may also remove locally stored data, so verify that important information is backed up first.

Does force restarting an iPhone delete anything?

No. A force restart simply reboots the device at the system level. It does not erase your apps, photos, messages, or other personal data.

Should I reset my iPhone if apps keep crashing?

A complete factory reset should not be your first solution. Try app updates, restarting, checking storage, reinstalling the affected app, and Reset All Settings first. A full erase should normally be reserved for persistent system-wide problems after your data has been backed up.

What should I do if only one app won’t open after iOS 26.7?

Check the App Store for an update, force close the app, restart your iPhone, and reinstall the app if necessary. If the problem continues, the developer may need to release an iOS 26.7 compatibility update.

Final Thoughts

If your iPhone apps are crashing or not opening after the iOS 26.7 update, begin by force closing the affected app, restarting your iPhone, and installing all available App Store updates. These steps solve many post-update app problems without affecting your personal data.

If the problem continues, check storage and network settings, offload or reinstall the affected app, and look for another iOS update. When several unrelated apps are affected, system settings or iOS itself become more likely causes. When only a single app crashes, an app-specific compatibility problem is usually more likely, and the developer may need to provide an updated version.
