Weird file & asset browser behaviour

Hey there,

I recently picked up Blender again intensely with 4.1 - the following things are beyond my grasp:

I’m trying to import and organize assets. When I open a file and want to save it as, for exaple, I see no files or subfolders within a folder. Only upon exiting and restarting Blender.

I’m trying to find assets I definitely have. But even if I search withing “All” assets, I can’t find them anymore. But that leads to my actual problem - sometimes, I type stuff in the search bar, no items are found. I do the same thing after restarting, works just fine. Or I find something, then search something else, and then the first item again, and “no items found”.

I do NOT have my assets on a cloud drive anymore. I stored them on an HDD, not SSD. I copied the entire folder as is from the cloud drive and simply changed the path in prefs.

What could be the reason for this behaviour? Or where could I find the source of the problem?
