Google likes to experiment on its users, so things do sometimes change temporarily and then change back. ??

its something about cookies, bcuz It happend again, even when I sign out, I still cant play videos... then I go right click -> view page info -> clear cookies and site data -> then it works, I sign in, it works, but I close that tab, go again for youtube and it dont work again, even when I sign out... so its not about google acc its about cookies

The "experiment" population often is identified by a cookie, which is why using a private window instead of a regular workaround can be an effective workaround.

What's odd is that you have the opposite symptoms that some other users report: they get the player but none of the rest of the page. Neither is good!
