Hi! I understand you’re seeing the "an error has occurred" message every time you open the MANGA Plus app on your Android 10 device, and force stopping or clearing data didn’t help. I’d like to help you get this sorted out.

Just to clarify a couple of things first:
- Are you using the official MANGA Plus app downloaded from the Google Play Store?
- Is your app fully updated to the latest version?
- Are you connected to a stable internet connection when you open the app?
- Has this error started recently after any changes like updates or device modifications?

Based on what you’ve tried already, here’s a step-by-step approach we can take next:

1. Check for App Updates: Go to the Play Store, search for MANGA Plus, and see if there’s an update available. Sometimes app errors happen because of outdated versions.

2. Clear Cache: Instead of clearing all data (which you tried), try just clearing the cache. Go to Settings > Apps > MANGA Plus > Storage > Clear Cache.

3. Reinstall the App: Uninstall the app completely and then reinstall it fresh from the Play Store. This can help fix any corrupted files.

4. Check Date & Time Settings: Ensure your device’s date and time are set correctly or set to automatic. Incorrect time settings can sometimes cause app connection errors.

5. Check Network: Try switching between Wi-Fi and mobile data to see if the problem persists. Sometimes network restrictions or unstable connections trigger errors.

6. Check for Device Software Update: Since you’re on Android 10, check if there’s any system update available. System bugs can also affect app performance.

If after all this the problem is still there, it could be an issue on the app side (server or compatibility issues). In that case, contacting MANGA Plus support directly or emailing [email protected] might be the best route.

Let me know what you find with the above, and I’ll guide you further! Are you satisfied with this approach so far?
