Right click context menu opens everywhere quickly - except Desktop in Windows 11

For some reason only the Desktop in Windows 11 slows to a crawl (approx 30 seconds) before opening but everywhere else it's only a second or 2. I haven't a clue why this is or what I can do to fix it. Suggestions??
Thanks-- Am using 12.30.1beta x64 currently but it was doing it previously also.

It's usually due to a shell extension something else has installed.
