For what it's worth, I've seen this problem intermittently for at least a year now, on multiple computers.
All 64-bit. Some Windows 10, some Windows 11.
At least one which has ONLY OneDrive for Business (that is, OneDrive from a Microsoft 365 Enterprise E3 subscription) configured - so the theory in one post about the problem being a bad interplay between co-running both the personal and business OneDrive clients probably can't explain all of the occurrences (though it wouldn't be at all surprising if that theory did explain some of the occurrences, of course; this one, very vague error may occur for more than one reason).
I happened to notice this just now at a time when OneDrive was quite busy bringing cloud-available files to local: an image management program aimed at a directory full of photos stored on OneDrive, not yet sync'd locally. That image management program window hung so hard on the I/O that I had to switch to another user to kill the process (Windows wouldn't even allow another window/ the task manager to appear above that image management program window, even though screen lock/unlock worked fine, and right-clicking on the task bar would successfully bring up the task bar context menu; it was quite weird). (The issue has occurred many times over time; not always associated with that image management program; so that's just an example of how the OneDrive problem can screw up everything else, it's not a suggestion that the image management program is doing anything wrong at all).
This most recent occurrence is on a brand new, original Windows 11 system that was just installed and set up less than one week ago, so "reset OneDrive", deconfigure, fix, etc, really shouldn't be related. It's almost surely a bug in the OneDrive client.
