Brightness, Nightlight, Infrared blaster does not work suddenly

I am unable to change the brightness, even the function keys and brightness slider does not work.

Night light does not respond

Infrared stopped working - Windows Hello stoppped working

Tried the following but did not work

Uninstalled display driver and re-installed it does not work.

Reinstalled windows

Updated all drivers.

I suspect that after some stupid update that rolled out caused all these isuues.

Can anyone help me out here.

Thanks!
