I have this issue after exiting and then relaunching the app - it seems that the camera is not correctly released for some reason (despite calling videoTrack.release(). Calling cameraCapturer.stopCapture() when the activity is destroyed (app is exited) solved the problem for me.

I suspect there’s some sort of race condition preventing stopCapture() from executing correctly, perhaps if you quit the app too soon after starting iniitialisation of the camera capturer, then the capturer is not released.

Is it possible a video track is being created twice? Once in onRequestPermissionsResult and once in onResume or are you only creating the track in one of those callbacks?
