Went to start my car and it gave me a loud squealing noise. Hit the gas it got louder and the battery charging failure notification popped up on the dash. I recently replaced my belt 3 weeks ago. Looked under the hood, the belt was not turning and it looked 50% thinner than when I brought it. Kinda looks like it's stuck on the tensioner. Tried to push it down and pull up the belt on the tensioner but it's stuck. So, where do I go from here? I'm scared to drive it because every time I start it it squeals louder, so how do I fix it?

Hello,

It appears the belt might have slipped causing it to wear off excessively and got seized. So when you start the car the belt does not rotate the alternator and other pulleys as designed.
First step would be to replace the belt.
Be sure to follow the routing diagram when replacing the belt (See below).

I have attached the replacement procedure including the diagram for your reference.

Please let me know if you have any questions.

Thank you.
