I am unable to access the link you posted, assuming is a video.(Forget it I was able to do so later on)
Anyways, if you are referring to the 5 windows that open when you click the Beta Features button (they eventually close when the last one opens), I wanted to say that this issue also happens to me and I am using Windows 10. For sure it’s a bug that they have in every device that can access Studio I would assume.
Sorry for the reply, the issue I have does indeed look different. I wonder what’s wrong with the Beta Features button:
