Camera suddenly stopped working - fixed itself

Everything was fine until last week. I have a MacBook Pro Sonoma 14.5 OS. Starting last week, when I turn the Zoom camera on during a call, it show my chosen background, the green camera light on the laptop turns on, but it doesn't broadcast - my face does not show live on the Zoom. It's just my background image. Help.

After posting for help, of course, this has now magically resolved itself.
