    wallybhI had the same issue in Windows build 19592 (insider preview). Just got an update today to version 19603 and voila - Teams is able to activate the cameras again!

I have the same issue. 

MacBook FaceTime HD Cam is working in every App, except Teams. Running on Bootcamp Win10.

It is weird because the green light turns on and it looks like it is working, but it stays black.

Sometims it even "gives up" telling me, Video "stopped working".

 

Strangely on top: When using "Snap Cam" without filters (likewise a proxy for the cam) it is working fine!

So it is definitively Teams / Win10 causing the problem.

 

Ah: And it stopped working only a few days ago. On Monday this week it was working.

    rolandoldenburg wallybh I have the same issue and set up as you (bootcamp running windows 10).  

    I've leaned that the camera issue only happens when I join a Google Meet or Zoom call prior to joining a Teams call.  For whatever reason, using Google Meet/Zoom prior to teams seems to cause the issue for me.  I have been able to temporarily fix the issue by booting back into Mac, joining either a fake meet call or Teams call (I do both just to be safe), hang up, then booting back into windows.  Upon logging into Teams, the camera seems to work again fine.  I can then reproduce the issue each time by joining a Meet call, hanging up, then joining a Teams call, which starts the process all over again...  I haven't been able to find any other fixes or luck with support.

      jofranst THANKS for that tip!!!! It works!

      When rebooting into Mac OS, starting a Teams-call, then reboot into Windows everything is fine again!

       

      And interestingly on top of that: I recognized that in the tool "ManyCam Virtual Webcam" it allows to de-/activate "Hardware acceleration". And that does seem to be the relevant thing here.

      When Windows/Teams is screwed up ManyCam only works with deactivated(!) HW Acceleration. So it must be related to OpenGL/Direct3D and/or GPU-Usage somehow.

        rolandoldenburg It seems the issue has resurfaced in version 1.4 of teams. I have about 15 computers with a USB camera from Hyper and non work with any version of 1.4 and latest version of windows 10 pro. As people reporting this issue earlier all of these computer can use that same camera for any other video application with no issues, including teams on the web. It's only teams desktop that does not detect the camera at all.
