I have it too. The image randomly freezes or the entire playback freezes.
But also regular video (not live) has problems, for example it skips forward a few seconds at random moments.
I don’t know if this is something to report on bugzilla. It’s hard to report this because I would have to constantly record my screen while watching YouTube to catch the random moment when it happens.

I have uBlock and SponsorBlock. I’m on Arch Linux.

Not only. This also happens when switching between TTYs.

I’m trying to move the setting to the boot stage, but it’s not easy.
