Function buttons (volume, brightness) doesn't work after recent update

[as]

Function buttons (volume, brightness) doesn't work after recent update: Thinkpad e14, kernel 5.15.0-53-generic. I'm not able to turn on functions working on keys F1-F12. FnLock (Fn+ESC) doesn't work either.

I found out that keys works from time to time, but I can't find out what makes them working and what makes them disabled.
