new MacBook - JK does not detect any webcams - yikes

[plsullivan]

I have a (literally) brand new MacBook Pro and JK "does not detect any webcams". I cranked up the photo booth app just to make sure the camera is working. All good there. The OS is Big Sur 11.1 (20C69). Any suggestions would be very welcome. I basically bought this Mac to jam with some friends. My other Mac didn't die but it's from 2009 and this was a good excuse to get a new one. However ... I really need to see those fretboards.
