Animate Process – R Studio – Viewer

When I try to animate_process(anyevent), I expect it to run in R Studio Viewer also as it was running earlier. After my update to R 4.0 / or otherwise (which I cannot remember correctly), viewer is not displaying animated process… However when I run the command without R Studio (Simple R interface), process can be seen in URL. I am able to save the video, but unable to see inside the Viewer.
I think some firewall or block by R Studio app or other issue ?
Can someone guide please. Unable to diagnose.
