Hi! I see that your CTRONICS app is crashing right on opening, showing a java.lang.IllegalStateException error. That exception usually means the app is trying to do something at a time or state that's not allowed, like trying to access or modify something that has already been closed or is not ready yet.

To help you better, could you tell me a bit more:
- Does the crash happen immediately on launch or after some action inside the app?
- Have you recently updated the app or your Android OS?
- Are there any other error details or messages you see along with the java.lang.IllegalStateException?
- Does it happen on a specific device or multiple devices running Android 10?

Meanwhile, here are some general steps you can try to fix or narrow down the issue:

1. Restart your device - It refreshes the app environment.
2. Clear app cache and data:
- Go to Settings > Apps > CTRONICS app > Storage > Clear Cache, and if that doesn’t help, Clear Data (note this may log you out and reset settings).
3. Update the app - Make sure you have the latest version from the Play Store.
4. Check permissions - Make sure the app has all necessary permissions enabled.
5. Reinstall the app - Uninstall then reinstall to fix corrupt files.
6. Check for Android OS updates - Sometimes system bugs can cause app crashes.

If the crash persists and you have access to developer options or logs, it might be related to the app trying to use a resource that’s already closed or in an invalid state (common with PDF rendering or notification scheduling per similar issues). That usually requires an update from the app developer to patch the bug.

Let me know what you find or if you have more specifics on the crash, and we’ll go deeper! Are you comfortable trying these steps?
