Camera Help

I have a new laptop and external camera running Windows 11.  I can turn the camera on and see video of myself, but in Zoom the screen is black. I have checked privacy settings. Camera is enabled and Zoom camera is enabled.  Meeting participants cannot see me.  The host can turn my camera on and off in the app, and I can click on share video, but it does not fix the problem.  As soon as I go to Zoom, my camera turns off.
