Camera freezes in Teams
This advice for people where the registry fix outlined by Sonia2020 didn't do the trick.
If Teams video is freezing right after connecting a call, then I've had great success with rolling back the driver for the Integrated Camera in Device Manager. This has worked even when it was an external webcam attached to the computer.
One other thing that has helped for the same issue has been Disabling GPU hardware acceleration in Teams Settings on the General tab.
For Martin390 where Teams video works but the USB document camera doesn't, I'd recommend looking for the external camera's device driver in Device Manager under Cameras or Imaging devices and roll back the driver. There's a good chance that some update threw a tilt in it's operation.
On a side-note, for people with other Teams video problems of lagging and freezing but not necessarily right from the moment they connect a call, there's one more area to check. Go to %appdata%\Microsoft\Teams\Cache and delete everything there. Teams cache seems to fill up quickly and can significantly slow down the app, most notably impacting video quality.
Finally, not for Christian_Stokes but if video is lagging/freezing in other apps as well as Teams, then it might be worth checking internet band-with which can play a significant role in video.
