Hello! I understand you're experiencing a problem with the Quran 13 Line app where it appears blank when you open it, and that reinstalling the app seems to provide a temporary fix. Let's work together to find a more permanent solution.

Here are a few steps you can follow to troubleshoot the issue:

1. Clear Cache and Data: Sometimes, accumulated cache and data can cause apps to malfunction. To clear the cache for the Quran 13 Line app:
- Go to Settings on your Windows device.
- Navigate to Apps or Applications.
- Find Quran 13 Line in the list and click on it.
- Look for options to clear cache and data. If available, do that.

2. Check for Updates: It's important to ensure that both your app and Windows are fully updated.
- Open the Microsoft Store and check if there’s an update for the Quran 13 Line app.
- Also, go to Settings > Update & Security > Windows Update and ensure your operating system is up to date.

3. Adjust Permissions: Sometimes, apps require specific permissions to function properly. Ensure that the app has all the necessary permissions enabled.
- Again, navigate to Settings > Apps > Quran 13 Line and check the permissions.

4. Firewall or Antivirus: Occasionally, firewall settings or antivirus software can interfere with app functionality. Try temporarily disabling these to see if the app opens without issues. If it does, you may need to adjust the settings of your firewall or antivirus.

5. Network Connection: Make sure that your internet connection is stable, as some features of the app may rely on a good connection to load content properly.

If those steps do not resolve the issue, the next option would be to reach out to the support team directly at [email protected]. Sometimes, there might be a known issue that they're working to fix.
