    Solution for running two separate terminal commands seem to work in here for me.

     

    Please a have a look.

Have a look at this thread. Its for an entirely different app but it might provide some insight into the root cause of your issue as it relates to MacOS Catalina and virtual webcams not working after an update.

    hackerx I can confirm unsigning the teams app doesn't enable virtual webcams. 



    sudo codesign --remove-signature /Applications/"Microsoft Teams.app"



    Does not do anything after restarting the system.

      I can confirm that it is a Teams issue only. If you install an older version of the app it actually fixes the issue, but then it breaks again within 24hours because Teams auto-updates (which you cannot turn off). 

       

      Microsoft, please fix this. You have made Teams worthless for those of us who have to do trainings with multiple cameras. This breaks Teams for many in the tech and EDU community.

        When Zoom had the same issue, it tooked like 3 or 4 days to them to release a new version with the solution to this problem. It has been passed 12 days since the problem was detected with Teams and still nothing. Please Microsoft solve the issue now.

    hackerx I appreciate the link! Attempting some of the recommendations did not address the issue, unfortunately. This appears to be directly related to the MS Teams update as the functionality was working directly prior to the update and not working after the update, with no updates to the OS or other Catalina-specific software in the interim.
