Restart Your Device:
A simple restart can help resolve temporary glitches. Turn off your phone, wait for a few seconds, and then turn it back on.

Clear App Cache:
Go to Settings > Apps > [App Name] > Storage > Clear Cache for each app that is crashing.

Update Apps:
Ensure that all your apps are updated to their latest versions. Outdated apps can sometimes cause compatibility issues.

Safe Mode:
Boot your phone into safe mode to check if the problem persists. This helps identify whether a third-party app is causing the issue. If the problem doesn't occur in safe mode, it's likely an app causing the problem.

Uninstall and Reinstall Problematic Apps:
If certain apps are consistently causing issues, try uninstalling and then reinstalling them from the Google Play Store.
