Hi there! I understand that you’re experiencing a blank screen when trying to open your BetterMe app. Let's troubleshoot this together.

1. Restart the App: Sometimes, simply closing and reopening the app can resolve minor glitches. Try swiping up or down on the app (depending on your device) to close it fully, then reopen it.

2. Check for Updates: Make sure your BetterMe app is up to date. You can check this in the Microsoft Store or the app's settings.

3. Restart Your Device: A quick restart of your Windows device can often resolve issues related to software that might be affecting app performance.

4. Reinstall the App: If the above steps don’t work, try uninstalling and then reinstalling BetterMe. This can help refresh its cache and fix any corrupted files:
- Go to the Start Menu, then find BetterMe in your list of apps.
- Right-click it and select "Uninstall."
- After it's removed, go to the Microsoft Store, search for BetterMe, and reinstall it.

5. Check for Windows Updates: Sometimes, your operating system may need an update, which can also affect app performance. You can check this by going to Settings > Update & Security > Windows Update.

Please try these steps and let me know if the issue persists. If you're still seeing a blank screen, we can explore more advanced troubleshooting options!
