This usually means that administrator's rights are required to delete these items.

No idea which process creates that, but I periodically observe the same situation (GUID-like directories which may only be deleted with elevated permissions) on my computers.

I usually clean them up via sudo pwsh -c vacuum, but, obviously, on your computer, it's up to you.

There's a plan to stop showing exception stack traces for such cases (#23), but I don't think anything else could be done with that regard. This is an actual error we're getting from the system when trying to remove these items. We may try to guess what's usually wrong and suggest the user to restart the program with elevation, though?
