Asus Laptop Windows 11 black screen when turn video on in meetings

[Josie26]

I have a Asus flip laptop running windows 11 when I start or join a meeting and turn on my video within a minute I have a completely black screen, it may then turn back on but will then go completely black within a minute.  Bizzare thing is that if I do Ctrl-Alt-Del and go to task manager video comes back and i can see the Zoom meeting screen. I have updated to the latest Zoom client which made no difference.  I have tried turing off hardware acceleration just in case, made no differerence.

Has anyone else had similar problems and have a solution?
