keyboard – Ubuntu 21.04 on laptop scroll lock dosen’t work

for some reason scroll lock doesn’t work on ubuntu 21.04 pressing it does nothing at all.

What I’ve tried:

reading several questions about same issue all leads to same thing:

Open terminal

xmodmap -e "add mod3 = Scroll_Lock"

and that doesn’t work, the only thing working is

cd /sys/class/leds/input9::scrolllock
echo 1 | sudo tee /sys/class/leds/input19::scrolllock/brightness

and that only works until i un-plug the keyboard or log out, also the number next to input changes everytime i un-plug it or log out
