KW100 keyboard not discoverable on windows 11 pc

I'm trying to connect my keyboard to my pc via bluetooth but the keyboard doesn't show up in the available devices. the keyboard is turned on and in pairing mode, i tried turning off bluetooth and turning it on again, restarting my Windows 11 computer, turning the keyboard off and on again, etc and nothing is working, my computer just won't recognize my keyboard. can anyone help please?
