Quicktime can't access my camera

Hello Brunn1,

We understand that you're experiencing an issue with QuickTime, and we want to see how we can help.

To help us get a better understanding of the issue, we’d like to ask a few questions.

1. What happens when you try to use QuickTime? For example, are you seeing a specific error message? If so, please let us know what the error says, as that can help narrow things down further.
2. Are you using the steps outlined in the following page to try and record a video in QuickTime Player? Record a movie in QuickTime Player on Mac
3. Did this issue begin recently? If so, were any changes made to your device or its settings before this began?

Thanks!

I have the same problem same device.

To reproduce the problem:

1. Open quicktime
2. Create record movie
3. See green camera light turn on
4. See a black screen in the recording screen window on the monitor
5. Optional: check with the down arrow to see if Facetime camera is checked but still notice that it's a black screen.

A few months ago I installed Bitdefender and Kaspersky, then removed them. I still have Malwarebytes free edition on my computer. Not sure which settings the Quicktime camera needs enabled. Please advise.
