Hmm haven’t seen that yet personally but I’m sure YouTube is always trying things to get around adblockers and probably A/B testing it on various accounts or countries. You could try making sure unlocks rules/definitions are up to date.
Unrelated but I also have been using sponsor block which skips over in-video sponsors which is nice. Though it’s community updated so very new videos might not have the sponsor segments marked yet.
I think the solution is to board up the room and leave it for future generations to rediscover and be horrified and mystified on turns
