probably the bearing is shot.

start the engine briefly without the belt

wiggle each pulley other thing that can happen is (rare) the chain guide can fail and make a racket - hope it's not that!!

Yes.....in one of the video clips there was a belt tensioner pulley wobble during the first part of the video. Just replace the pulley the rest of the tensioner is probably OK.

And concur....just remove the belt which will eliminate all pulley noise
