I am trying to adjust the brightness of my computer and it's not allowing me. I have to either restart the computer or shut it off and turn it back on for the brightness to go back to normal. How do I fix this?

Getting Keys to Work:
(Applies to Intel-Based Macs Only) Sometimes when changes are made to the system(i.e. updates), system configurations (i.e. for Ports) become manipulated, technically. So, reset the SMC and NVRAM.
When you boot into Safe Mode, items load by default, with certain settings and caches set aside. So, boot into it, and then see if it works. Go here: Start up your Mac in safe mode - Apple Support
See if creating and logging in as a new administrator does the trick. There may be something misconfigured in your current user - something that is getting in the way. Go to: System Preferences > Users & Groups > Unlock > Click: "+" > Create the new administrator
