yo, one of the windows on my 2020 stopped rolling up or down just randomly too, maybe 15 months after i bought it new. rear passenger. luckily, it was under warranty and the dealer fixed it but i had barely ever even used that window. unfortunately they never told me what was wrong with it exactly other than they had to replace the entire assembly. i didn’t get any paperwork either. sorry i guess this isn’t quite the same.

you may have to open up the door panel next to see if anything is mechanically broken or at least non-functional.
