Crash every time the app is opened

[s1m-e0n]

Every time I installed the Nextcloud app at some point it would crash with the error message below. The crash would then occur everytime the app is opened, clearing the cache or app data wouldn't help. I have reinstalled the app at least 10 times already, so it is very frequent. This occurs on the dev build as well.

Steps to reproduce

There is no consistent pattern, it will randomly happen. I think though, that it always happened on a loading screen, so when the app was waiting on something, though I'm not entirely sure. There are no settings that I changed, the last crash occured pretty much right after I logged in.

Expected behaviour

• The app does not crash. The app won't crash every time it's reopened.

Actual behaviour

• The app would unpredictably crash while using it, even if the thing you were doing worked previously. Then, after reopening the app it crashes again with the same error massage. This does not affect background sync however, the background sync will continue working.
