Hello BjrnN,

Try to reset OneDrive, see if it helps:

1. Open a Run dialog by pressing Windows key + R.

2. Type %localappdata%\Microsoft\OneDrive\onedrive.exe /reset and press OK. A Command window may appear briefly.

3. Manually launch OneDrive using Cortana or Windows Search. Type OneDrive in the search box, and then click on the OneDrive desktop app. Re-setup OneDrive.

Let us know if this helps!
