[Bug] Crash : Ankidroid crashes on performing a force sync from anki web to ankidroid.

[THElegend5]

Reproduction Steps

• Updated from 2.15.6 (Play store ver.) to 2.16alpha58
  and when i opened a card i started getting "failed to load : failed to load ...."
  

• So i decided to use check media which instantly crashed the app.

• After that i decided to force sync from anki web to ankidroid which also crashed the app.

• Decided to check if my library was corrupted for some reason or not by downloading a parallel of 2.15.6 on which it seemed to work perfectly, updated the parallel to alpha58 and it was also crashing.

• The alpha also doesn't seem to be detecting the backups neither is it creating them properly from what i can tell.
  
  The only one which was good on 16/04 was made by the stable parallel.

• Just to confirm if the problem was from this alpha or from before this I decided to test on alpha 56 parallel and got the same issues uninstalled the parallel and installed alpha 55 parallel and there wasn't a crash this time, decided to update 55 to 56 and test again and there wasn't a crash, same with from 56 to 58.

• Btw I did try to reinstall main alpha58 directly when i was originally getting the crash before the above point happened and the crashes still happened. I thought i did but seems like i hadn't installed it directly and when I just did it seems to work fine on installing directly and this only happens if you update directly from 2.15.6 to 2.16 Alpha56/58/59.

• Have confirmed that it doesn't crash anymore on main after uninstalling 58 and installing 55 then 56 and 58 again after that.

• Backup still don't seem to be being created properly but am not sure yet, so will confirm after I am. It is detecting backups again and the backups are being created properly.

• Also half of this happened while writing this so it might seem like a story.

Expected Result

App checks media , directly syncs from anki web to ankidroid , Backup being created properly.

Actual Result

App crashes if you have updated directly to alpha 58 or installing alpha58 directly over current library.

I have been doing a lot of media check testing (#12026) and force syncing (#11849) so these code paths were recently exercised a lot and while I did see problems myself I think they are all fixed now in 2.16alpha78 - we can reopen if they recur of course
