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.
I recommend KDE Connect, it also has this function. :)
But sometimes I use this and sometimes I use that feature.
