Hi there! I’m really sorry to hear that the Heja app keeps closing on you. Let's try to find a solution together!

To get started, could you please let me know if you’ve already tried any troubleshooting steps, such as restarting your device or reinstalling the app? If you haven’t tried those yet or if you did and they're not helping, I can guide you through some steps to get it working again.

Here are a few basic troubleshooting steps we can start with:

1. Restart Your Device: Sometimes a simple restart can resolve temporary issues.

2. Update the Heja App: Go to the Google Play Store, search for Heja, and see if there's an update available. Keeping the app updated can prevent crashes.

3. Clear App Cache and Data:
- Go to your device's Settings.
- Select “Apps” or “Application Manager.”
- Find Heja in the list and tap on it.
- Tap on “Storage” and then select “Clear Cache” and “Clear Data.”
- This won’t delete your app data, like your login information, but it will reset the app to its default state.

4. Reinstall the App: If none of the above steps work, try uninstalling and then reinstalling the app from the Google Play Store.

Give these steps a try, and let me know how it goes. If the issue persists, we can explore more advanced solutions!
