### Bug description

Updating to version 33.0.0, there is a folder sync bug that affects everything.

clicking on "sync now" does nothing. 
Going into the settings, we can see this:

after pressing the text "Hier klicken" and selecting the same folder as before, the issue disapears. 

I had this bug today on two different macOS 26.3.1 clients.
