Sounds like one of your accessory drive pulleys yeeted a couple ball bearings.
Remove the belt and spin each pulley by hand.
Yeah I’m thinking a pulley. Dealing with the belt is a PITA… Ugh.
Tip- Take off the engine skid and loosen the tensioner from under the car- you'll have more leverage (access for a longer bar) and way more room.
Oh yeah just drop the front skid plate. Piece of cake if you live in Arizona I guess.
Just buy a serpentine belt tool:

$30 on amazon. It's worth it. Good for other random tasks as well.

I agree there is not a lot of clearance but belt can be removed from the top. I replaced my alternator a couple of months ago which called for belt and idler pulley to be removed.
Curious why'd you remove an idler pulley?
I had my alternator off last week and I didn't need to do that.
