Mac OS Catalina is Broken

[musicfactorystudios]

When I updated my 2019 15 inch Macbook pro (9750H CPU & 555X 4gb) Laptop to the latest MacOS 10.15.6 it seems to have broken ffscreencast. The terminal output after a --test gave me this
ffscreencast --test
[OK] Operating system supported: Darwin
[OK] ffmpeg found: /usr/local/bin/ffmpeg
[ERR] [OSX]: AVFoundation not available in ffmpeg.
- Desktop recording not possible.
- Sound recording not possible.
- Camera overlay not possible.
ffscreencast worked perfectly before the update and I update homebrew and all of my package daily so I tried removing ffscreencast and ffmpeg then reboot then reinstalled both ffscreencast and ffmpeg even after another reboot ffscreencast isn't working. ffmpeg is working. I'm not a developer so I don't know how to troubleshoot this issue so I thought I would post it here. Thank you for all of your hard work on ffscreencast and hopefully this issue can be resolved. If you have any further questions you can email me at [email protected] and I will gladly help in any way I can.

I'm seeing the same error.

Running ffmpeg -f avfoundation -list_devices true -i "" gives me this output:

ffmpeg -f avfoundation -list_devices true -i ""
