Crashed in background while questing multiple uploads manually for uploading with bad network connection

### ⚠️ Before posting ⚠️

- [x] I've [searched for similar issues](https://github.com/nextcloud/android/issues) and didn't find a duplicate.
- [x] I've written a clear and descriptive title for this issue, not just "Bug" or "Crash".
- [x] I agree to follow Nextcloud's [Code of Conduct](https://nextcloud.com/contribute/code-of-conduct/).

### Steps to reproduce

1. Upload files via sharing feature of Android (I guess not related but well) like 4 or so one after another.
2. Upload files via the integrated file upload in the app. Three files at once.
3. Do something else ak let app run in background.

Do all this with bad network aka interruptions and slow net.

At some point nextcloud was there (maybe I was viewing the target sir) and showed me the crash screen.
