I use Firefox + ublock and noticed the youtube comments dissappearing as well.
Im not knowledgeable enough to really understand what I’m actually doing when i use this “fix” but - i noticed if i disable cosmetic filtering in Ublock, comments reappear, but they dissappear again when enabling cosmetic filtering again.
Not sure if that’ll apply to you but that’s about all i know.
It’s what they do to the citizens of china, uyghur or not, and the surrounding countries, instigating shit it internatinal waters, etc. Evil doesn’t have to do anything to me personally for me to hate it.
