Hello RmKLA,
Thanks for that info and choosing the Apple Support Communities. Based on what you stated, it seems you are having issues with the built-in camera on your MacBook Pro in Photo Booth. You can figure out if unexpected behavior is related to a user file or setting by trying to reproduce the issue from another user account. This process includes creating a new user account, logging in to it, and testing for the issue.

Next, use safe mode to start up your Mac so that it performs certain checks, deletes system cache files, verifies your startup disk, and attempts to repair directory issues if needed. Log into your user account and test the issue while in safe mode and then restart normally and test the issue again.
