No video (black screen)

Has anyone else run into this? Zoom recognizes when my camera is connected but shows only a black screen in place of the video. I don't remember exactly when this first happened, but I think it was sometime in March.

• I've tried everything on this page - nothing worked. The other community pages I found that address this issue haven't helped either.
• None of my other video software is having a problem with my camera.
• I've also tried downgrading as far back as v 5.17.10 but the issue persisted.
• Mac privacy settings allow camera access to Zoom.
• Nothing looks remiss in my camera settings in Zoom.

I'm on a Mac and use an external camera (the internal camera was water damaged over a year ago, and I've been using this one ever since).

Any suggestions?
