Serpentine belt

Not even 5 minutes after pulling out of my driveway I get a burning rubber/plastic smell coming from my vents, I’ve lifted my hood as soon as I smell it. I follow my nose and it leads me to my serpentine belt every time. I replaced my old belt and looked for seal leaks from my engine, coolant line leaks, and power steering leaks nothing looks wet under the hood, no puddles under my car or wet spots anywhere. I looked for foreign objects, plastic bags, anything that could’ve flew up and got stuck on something hot and started melting. I’m thinking it’s one of my pulleys but my power steering works fine, A/C works fine, alternator is still charging my battery just fine. Please help.
