Can you share a little more about the Camera model, Desktop environment (Windows/Mac, version), and desktop/laptop model?
If you're trying to use both Teams/Skype at the same time as Zoom the camera and Mic will not be available to control.

Zoom black, Skype OK!

Same issue on an HP desktop with windows 10.  On the desktop the camera works fine when I open it, takes pics and video, but all I get is a black screen even though it says it's on. Screen share worked fine, it was just the camera.
