Meet.jit.si does not go beyond 'Jitsi meet needs to use your microphone and camera' page

I am trying this service for the first time and it promises to fulfill everything that i need but only if it starts.
I go to meet.jit.si and hit ‘go’ to start a VC. Chrome asks for permission to allow camera and microphone. Allowed. The screen still says ‘Jitsi meet needs to use your microphone and camera’. Even after allowing the permissions and I can see in top right corner there’s a camcorder button which means permissions are on, nothing happens on screen.

Please help. Need to use this urgently. Hate that Hangout on Air is no more. Need this one to work.

Hi and welcome!
What browser and version do you use? Which OS?

Google Chrome - Version 77.0.3865.90 (Official Build) (64-bit)
OS - WIndows

Please help.

The only option for us to be able to investigate further is to ask you about uploading your JavaScript console logs from the browser from a problem session.
Also does https://appr.tc/ work for you?

Here’s the log. Appr.tc also just gives a black screen once i allow the permissions. Pls help.

Nothing suspicious in the logs. And if Appr.tc is failing the same way it can be a problem with the camera or drivers or chrome itself and there is nothing we can do about it.

I have read several threads of same issue other users are facing who are using windows 8.1+ chrome. Is that a known issue? must we all upgrade to windows 10??
