ublock and youtube are at war. My advice? I don't use ublock. I use a combination of adblocker and ghostery. Between the two of them Youtube hasn't won yet
it should work! i use a bunch of different apps that tackle privacy from different angles. ghostery is a good one, and so is privacy badger. ublock origin has yet to let me down.
and i would recommend "enhancer for youtube" because it has a lot of settings you can customize for the site as a whole. no comment section? hide the shorts? put a loop button by the play button? yes and more
Ublock is such a commonly used one and they've been in an arms race with YouTube for a while now. Though as a note I've seen on tumblr before, if you have copy-pasted custom YouTube blocking/filtering code into it, it may help to delete that and update ublock. It's more reliable to let it do it's pushed updates.
