Blank Screen after marking as favorite

Marking an entry as favorite in the app resultiert in a blank white screen.
Back button exits the app and new open/security login required (fingerprint in my case)
Device moto g7
Android 10, german

Same thing happens when just unlocking the app with fingerprint sensor.

1. Open the app
2. Prompt for fingerprint appears
3. Use the fingerprint sensor of the device (*)
4. Screen gets white (UI completely empty)
5. Back button of device closes app

(*) Also happens when I cancel the fingerprint input to use the PIN instead

Tested with Android 7 and Android 10. Issue exists on both devices.

PS: resetting the app completely (deleting app storage) and starting from scratch fixes the issue.
