In my case the video feed provided by the virtual camera stalls.  This happens with both virtual cameras I have: obs virtual camera and Shoot USB camera. The only way to restart the video feed is to use the integrated FT camera. After quitting and restarting Zoom, a crash warning is displayed. Looking in the console logs, in the list of crash reports, I see that the application which crashed is caphost. I am using  Zoom version 5.14.2, MacOS Monterey 12.6.5 and an 1,8 GHz Intel Core i5 processor.

I resolved this issue for myself by lowering the frame rate in OBS to 25 frames per second (PAL). After making this adjustment, everything proceeded almost normally.
