Bios flashback not working

Hi all, just finished my first ever pc build and went to flash the bios as I have a ryzen 5800x. My motherboard is an Asus Tuf gaming x570 pro (wifi) and I’ve followed the instructions to update the bios in both the manual and online with no success. The bios light keeps flashing constantly after I push the button with the usb inserted.

Things I’ve tried/troubleshot: Waiting over 20 minutes to see if it was slow, verified my usb is in fat32 format, verified the bios update file was the correct name per the manual and website.

Is there something I’m missing to make the flashback work? Should I try an earlier bios version maybe?

Im about out of ideas how to make it work since it’s my first build, and I’d rather not have things breaking on the ride bringing it to micro center to have them look at it.
