Hi! I see that your Rolling Sky app crashes right on the white CheetahMobile screen. Thanks for sharing that detail; it helps narrow things down. Could you tell me if this happens right after launching the app every time? Also, have you tried any fixes so far, like restarting your device or updating the app?

While you answer, here’s a simple plan to try:

1. Restart your device. This clears temporary glitches.
2. Clear Rolling Sky’s app cache and data on your Android 11 device:
- Go to Settings > Apps > Rolling Sky > Storage & cache
- Tap Clear cache first, then if issue persists, tap Clear storage/data (note: this deletes saved data within the app)
3. Check for app updates in the store and update if available.
4. If you installed the app from outside official sources or as an APK, uninstall and reinstall it from a trusted source like Google Play Store. Sometimes unofficial versions cause crashes on startup.
5. Confirm your device has enough free storage and RAM available, as low resources may cause startup problems.

If you have tried these or something else, just let me know and I can help you dig deeper. Also, if you can share the exact device model, it helps tailor more precise advice.

Are you comfortable trying this and telling me how it goes?
