Hi there! I understand your Work app isn’t opening at all. To help you better, could you tell me if there’s any error message when you try to open it, or if it just stays stuck or closes immediately? Also, have you tried any troubleshooting steps already?

Meanwhile, I can guide you through some steps that usually help with app opening issues on Android 10:

1. Restart your device: Sometimes, a simple restart clears temporary glitches.
2. Clear the app cache and data:
- Go to Settings > Apps or Apps & notifications.
- Find the Work app in the list.
- Tap Storage, then select Clear Cache first. Try opening the app again.
- If it still doesn’t open, go back and tap Clear Data (this will reset the app and may require you to sign in again).
3. Check for app updates: Open Google Play Store, search for the Work app, and see if there’s an update available. Updating can fix bugs.
4. Uninstall and reinstall the app: This can resolve corrupted files.
5. Check your Android system update: Go to Settings > System > Advanced > System update and make sure your device is running the latest version available.

If after these steps the app still won’t open, let me know if you’re connected to a work network or VPN, or if there’s any special configuration your company uses, since sometimes network restrictions interfere.

Are you able to try these and update me on the results? That way, we can narrow down the cause and find the best solution for you.
