Additional features, settings, or issues not covered by specific Microsoft Teams categories
I have been researching this issue for 2 days to no avail but your suggestion has worked thank you :)
Only thing I would add that was different for me was after the driver installed, it showed in Device Manager under camera. I then opened Teams and had black camera again, switched back to device manager and it had changed back to imaging device. Then I did the step of driver roll back which fixed the issue.
