NewPipe app is a good one, or Tubular if you want sponsor block too (though you can’t comment or like videos etc. on either). But if you want to use the actual YT app, the solutions in the other comments are good. I assume that setting up a Pihole or some other ad-blocking DNS could also work.
I got past it because it happened to throw a place from my country. And there was also a flagpole with a flag on it to really drive it home. XD
