Does anything show up in device manager when you plug it in? Have you tried another cable (have to go down every weird route here, because who knows). Fresh Windows or not, there are posts going back years and years (outside of this forum) of people having keyboards that only don’t work on one computer and work fine on all the others they try.
I’ve killed PCBs before (literally while standing up due to shoddy ESD protection or lack thereof, who knows) that would still light up and would still make the USB sound in Windows but were, for all purposes, dead.
