Keyboard backlight doesn’t work

Greetings,

I have an HP Envy, and I am using Fedora 37 Mate. The keyboard backlight never lights up. Some info:

None of this worked. Interestingly, the keyboard backlight works on Manjaro Linux.

Any help would surely be appreciated!

The keyboard backlight is controlled by the Window-F4 key. Once you hit that, it works. No other steps are needed.
