External Webcam Not Working on Zoom - Black Screen

My external webcam was working fine with Zoom for months and then all of a sudden sometime in the past two weeks, it stopped working and instead my video is a black screen to participants and to myself. I tested this same external webcam with Google Meets and it's working fine on Google Meets so it's definitely something with Zoom.

My built in Mac Air laptop camera does work with Zoom but I cannot use it for meetings because it is damaged and I look blurry which is why I have been using the external webcam these past few months for Zoom meetings.

I tried the following to troubleshoot: uninstall/reinstall Zoom, upgrade my Mac software, restart computer, go into Zoom video settings to check everything; check my privacy/security settings to make sure Zoom has access to my camera.

Anyone else have a similar issue or know how to resolve?
