Video stopped working after "upgrading" to MacOS Monterey

Hi - today after “upgrading” my Macbook to MacOS 12.3.1 (21E258), I can no longer stream video within the TOR browser. I let TOR keep itself up to date so the version I was using is whatever version is the current release.

I tried uninstalling and reinstalling, as well as installing the Alpha release, but with no success.

When I try to play video, just as an example from, audio plays but the video never updates beyond the thumbnail that’s displayed on the site. It’s the same for all sites including YouTube.

The standard Firefox browser behaves normally.

Looking at the console messages was not very informative, probably because I don’t know what many of them mean.

I’d be glad to provide more information or logs at your request.
