Hi there! I understand that you're having trouble with VITA stopping during the export process. Let's figure this out together. Could you provide more details about when exactly it stops? Is there a specific error message or is it freezing at a certain point?

In the meantime, here are a few general troubleshooting steps you can try:

1. Free Up Storage Space: Make sure there's enough storage available on your device. If your storage is full or nearly full, it can cause issues while exporting. You might want to delete unnecessary files or apps.

2. Clear App Cache: Sometimes, the app's cache can lead to performance issues. To clear the cache, go to your device's Settings > Apps > VITA > Storage, then tap on Clear Cache.

3. Restart Your Device: A simple restart can sometimes resolve temporary glitches. So, go ahead and restart your Android device.

4. Update the App: Ensuring that VITA is up to date can also solve various issues. Check the Google Play Store for any available updates for VITA.

5. Check for Device Overheating: If your device is overheating, it can interrupt the export process. Ensure your device is cool and try the export again.

Please try these steps and let me know how it goes! If the problem persists, we'll dig deeper into the issue.
