Hi, I tried the V4L2 driver with Buster which worked OK on a Pi4 4 GB then I tested Bullseye with the legacy mode and the same V4L2 driver ( veyecam2m ver 5.10.63) and that worked OK too.
I was previously testing with a Pi 3A which I would like to work but that does seem to have a problem with the v4L2 driver with both OS's.

With this fix it seems more reliable but it did crash again last night leaving a veye_raspistill Zombie. Short stack trace:-
