Unable to adjust brightness

I have been unable to change my Mac display for a while now, the display settings doe not show any options for brightness.

The display option in the control centre is greyed out and can't be moved.

When I try to use the function keys to regulate brightness it does not change anything

Also using the brightness option on my touch bar doesn't do anything.

So my display is constantly at its brightest and it drains my battery

I've tried to reset NVRAM but it still changes nothing.

I thought updating to Ventura will fix the problem but it didn't

I'm all out of options, Pleaseeeeee help.

MacBook Pro 13″, macOS 13.1
