To resolve the crashing issue of the app you are experiencing, follow these detailed steps:

1. Restart Your Device: Simply rebooting your phone can often resolve temporary glitches. Hold down the power button and select "Restart."

2. Update Your App: Ensure that you are using the latest version of the app. Open the Google Play Store, search for the app, and check if an update is available. If so, download and install it.

3. Clear App Cache and Data:
- Open Settings on your phone.
- Navigate to Apps or Applications.
- Find the problematic app and select it.
- Tap on Storage.
- Choose Clear Cache first, then Clear Data. Be aware that clearing data may remove any unsaved progress in the app.

4. Check for System Updates: Make sure your Android operating system is updated.
- Go to Settings.
- Tap on System > System Update.
- Download and install any available updates.

5. Free Up Storage Space: Low storage can cause apps to crash.
- Go to Settings > Storage.
- Delete unnecessary apps, photos, or files to free up space.

6. Check App Permissions: Sometimes, the app may need permissions to function properly.
- In Settings, go to Apps > select the app > Permissions.
- Make sure all necessary permissions are enabled.

7. Reinstall the App:
- Uninstall the app by going to Settings > Apps > select the app > Uninstall.
- Reinstall it from the Google Play Store.

8. Disable any Battery Optimization: Battery saving features can impact app performance.
- Go to Settings > Battery > Battery Optimization.
- Select the app and choose "Don't optimize" if available.

9. Check for Conflicting Apps: Other apps might be causing conflicts. If you’ve recently installed new apps, try uninstalling them to see if the crashing stops.

10. Factory Reset (Last Resort): If all else fails, a factory reset will resolve software problems but will erase all data on your device. Make sure to back up your data before proceeding.
- Go to Settings > System > Reset options > Erase all data (factory reset).

If you have tried all these steps and the app continues to crash, the issue might also lie with the app itself, and reaching out to the app's support team could be beneficial.
