Punkston TH61 on PS5

I have a Punkston TH61 that I'm trying to use on my PS5 but it wont work. When plugged in it says "Keyboard connected" and vice versa. The lights flash for a millisecond and then turn off and it doesnt respond to any keys. I've tried going in the punkston software for a firmware update but its already up to date. Anyone got a fix
