Windows unexpected restart caused by virtual/blur background

I recently upgraded my pc motherboard, processor and memory.

It began randomly restarting. I narrowed it down to Zoom.

I changed OS. (Win 10 to 11) Still had the problem.

I changed cameras. Still had the problem.

I changed various video settings. No change.

I changed video cards. No change.

I tested the ram - it was fine.

Then I noticed that the restart happened when I turned on "blur" background.

I've tried other virtual backgrounds and they also cause a restart. Sometimes it happens within seconds, sometimes takes a minute or two.

I looked at these forums but did not see any posts related to this problem - so here you go.

Please fix this Zoom.
