camera stopped working since recent update

I have the same problem. Did the update on my Mac and now my external camera doesn't work. Works fine on other Mac programs but no longer on zoom.  In trying to figure out the problem I saw a message that zoom isn't compatible with my OS. I gather this means I have no choice but to update my OS.  Not a problem for me but for some this will literally mean buying a new computer if their hardware won't support the latest version of the OS. 

Also, I got a security message when logging into a meeting this morning (when I discovered the external camera doesn't work) saying it was the first time I launching the application called zoom and was I sure I wanted to proceed. This struck me as odd and then boom, the camera was a scrambled / garbled image.

Is there a way to revert to the previous version of zoom?

Have the same issue. No one seems to have an answer.  I have no video and or sound. Happened right after the latest update.

I am having the same issue. Since the update, Zoom no longer recognizes monitor's built-in camera. Worked fine before the update (PC running Windows 10). Zoom needs to fix the issue.

Same problem here. The update just forced itself on my computer but my OS won't support it. ZOOM< you gotta do better and allow people to use the version that works for their OS. I can't update my OS or I will lose my QB program among other things. If I can't roll back to the previous zoom version then I guess I'm done with zoom:(
