Can't Adjust Brightness

The brightness toggle from the Control Centre is greyed out and won't let me adjust the brightness. I can change it from settings and using the touch bar, but not the control centre.

It's just a bit annoying because that's how I usually adjust my brightness.


I've tried turning it off and on again, tried updating the computer, tried turning dark mode on/off, tried turning night shift on/off.


This is what it looks like:


MacBook Pro 13″, macOS 11.4

You do not say what exact Mac this is...


If it is Intel processor—Try resetting the SMC http://support.apple.com/kb/ht3964
