LogiTech webcam not working on only one account

I recently got a new LogiTech webcam for my daughter's virtual school. Last week, the webcam was working fine for everyone. As of this morning (Monday), the webcam is no longer working on her account (non-admin), but works just fine on my account and my wife's (both admins) (in Zoom, Facetime, PhotoBooth).

When we're in my daughter's account though, Facetime gives an error about not receiving video from the camera. In the Zoom settings, Zoom can pick up audio from the camera fine, and lists the camera as the select video source, but the actual video is black. In PhotoBooth there is an error stating there's no camera connected (or something like that - if the exact error message matters I can go check it).

I checked the Privacy settings for her account and under Camera "Zoom" is listed and checked. Not sure how to add another app or if I even have to.

Nothing has changed since last week...

... and yes I did try restarting the computer.

Any suggestions on why a camera wouldn't be working with just one account?
