Uninstalling and reinstalling is one good idea. Can you delete the application from your application list on your mac and try reinstalling. Is there another computer you could test on to see if you get the same result? Do you need to re-enable a camera permission somewhere?
I am experiencing the same issue. The webcam and both buttons are grayed out and cannot be selected. But the screen record only works and the webcam works if you choose it from the "record" menu on the studio page.
Running macOS Big Sur 11.0.1 on a MacBook Pro.
I also reinstalled the Screen Recorder app.
In my settings > Privacy > the Screen Recorder app has permission for camera, mic, and screen record.
I have been wondering if this issue is related to Big Sur. Did you both possible update to Big Sur around the same time this started happening with Studio?
I updated last week and didn't need to use Studio until today.
It is likely related to the new OS, but unfortunately, the responsibility lies with Instructure to make their stuff work with Apple... not the other way around.
Here is a video of my experience today
Yeeesssssss! Thank you for going to the trouble to record the problem and your efforts at troubleshooting. This is exactly what I've experienced.
If the issue is indeed that Studio isn't working correctly with Big Sur, then you are absolutely correct that it is Instructure's responsibility to get things working correctly. I'll check with our friends in Support to see if there is a known issue with this. Thank you for the video documenting your experience. That should be helpful in figuring out what is happening.
OK, I heard back from one additional person who is running Big Sur and using Studio and they also said those two buttons are not working. I also checked with Support and it doesn't look like anyone has reported this in a support ticket. Would one of you mind filing a ticket and sending me the ticket number so I can can ask to have it escalated?
