Host's video no longer works on some established invitations

[CBB]

For several months, people have been using the same meeting link which is designated as recurring and for an unspecified time. Over the past few weeks, my video on a few of these calls has been blocked. This is not so for all calls even on the same day. Can anyone tell my why this is happening and how to fix it? I've even tried sending a new invitation link to these same people and it doesn't work. Thank you.

I have the same problem. I turn on my camera and it shows a black image. Sometimes the problem is there, sometimes not. It can't be the camera because it always works with teams. And the problem is also present whether I am host or not. It also doesn't matter if I'm logged into Zoom or logged out and taking part at a meeting as an unregistered person.
