Well, the only part you have not changed is the belt. As long as all pulleys, spindles, alignment, etc. are good, it should be good with a new belt. Old belts that get twisted sometimes don’t work once they are compromised.
I saw this once. I think one of you pulleys got pushed to far up or too far down and the belt has a steep angle going into or out of the engine pulley.
