Bug Description
Apps like OBS, which use v4l2loopback to create virtual cameras, have started losing their ability to create virtual cameras. In the case of OBS, it's able to create a camera one time. When the camera or app is "shutdown" the camera is unable to be created again unless a user manually removes the modprobe rule with "sudo modprobe -r v4l2loopback"
Ubuntu 20.04 comes with "0.12.5-1ubuntu1". That version seems to exhibit this behavior.

The author of v4l2loopback indicates this "is a problem with Ubuntu specific modifications" and it should be reported here.
