⚠️ Before posting ⚠️

• This is a bug, not a question or an enhancement.
• I've searched for similar issues and didn't find a duplicate.
• I've written a clear and descriptive title for this issue, not just "Bug" or "Crash".
• I agree to follow Nextcloud's Code of Conduct.

Steps to reproduce

1. I press the + button and press upload files.
2. I choose sort by newest first and it crashes.

Expected behaviour

I should be able to sort by newest first without the app crashing.

Actual behaviour

The app crashes when I try to sort by newest first. Some of the files are actually sorted already, but aren't appearing, so when I press newest first, it tries to fetch and load and sort, but immediately crashes.
