Anyone else having problems to play youtube videos within Safari in the Big Sur Beta 10?

No matter what video I choose, it always states an error occured. Only happens since Beta 10.

Confirmed that "All you have to do is disable "Develop tab -> Experimental features -> VP9 decoder", and then restart Safari" fixes the issue. Thanks, @Arun_Kudiyal.

Same issue here, Safari 14.0.2 on Big Sur 11.1. Disabling VP9 decoder does not help.

Same issue here, Safari 14.1 on Big Sur 11.3, Disabling VP9 doesn't help. I am now using Opera to watch YouTube. This has been going on since the Beta came out in August.

I installed Mac Os 11.5.2 today, tried all the solutions above, and still had the same issue with Safari not performed youtube well, so lagging.
