Anki-android: Crash when review ends

[idkw]

Reproduction Steps

I'm currently using 2.13alpha2 and most of the time (~4 out of 5) the app crash when finishing reviewing a deck. Then if I open the app again the review seems to have been entirely forgotten.

I have tried uninstalling, reinstalling, clearing cache, clearing data but the issue remains.

I have sent the error reporting crash report every time it occured but I don't if you receive it or if if I can do anything to help you investigate.

Expected Result

The app doesn't crash and saves the review result.

Actual Result

The app crashes and doesn't save the review result.

Debug info

AnkiDroid Version = 2.13alpha2

Android Version = 10

ACRA UUID = f8db4366-6f05-4d91-baf0-21511c8d83c0

We have been watching the reports closely and I think they are all identified at the moment, with one fix already made that is unreleased - should be released today as 2.13alpha3
In the meantime you may want to install 2.12beta5.A (the parallel 'A' build) on your device so you have a stable reviewing experience https://github.com/ankidroid/Anki-Android/releases/v2.12.0beta5

Thanks, I was able to review my decks using the parralel A version 2.12beta5

Great! We are obviously working on fixing the underlying issues - but especially for people on our alpha track we really value your testing and don't want you to have to hop off alpha and maybe never get back on. Good to have an interim solution while waiting for the next release :-)

@idkw This should be fixed in alpha3, please let us know if it still occurs.

Thanks so much for testing!

Just tried reviewing my decks with 2.13alpha3 and the issue appears fixed, no more crash when finishing a review
