A. 1. Clear app data: Go to Settings > Apps > Happymod > Storage > Clear Data. This will reset the app and may resolve crashing issues. Note that this will erase any saved settings or preferences. 2. Check for device storage: Ensure your device has enough free storage space, as low storage can lead to app crashes. Delete unnecessary files or apps to free up space.

B. 3. Update your device: Make sure your device's operating system is up to date, as updates can improve app stability.
