Unable to Change Screen Brightness of Laptop


So I'm not sure how long this has been happening but for some reason, I can't change the brightness on my laptop screen. I have linked a picture and as you can see, my brightness says 0% and that I can't change it, however my actual brightness is at 100%. I have looked around everywhere and the only responses I have found don't work for me. Here's a list of everything I have tried:
- Reinstalling Display Drivers
- Rolling Back Display Drivers
- Reset Settings on UWT4
- Power and Battery Settings
(UWT4 or Ultimate Windows Tweaker 4 is a customizer for Windows 10 and I thought that might be the problem but it wasn't)

If anyone has any suggestions on how to fix this, it's greatly appreciated! Thanks! -

No volume bar when changing volume level and changing brightness causing lag

A fix for Fn key control for volume would be tied to ASUS function. I suggest you google "fn key not working on ASUS (Model)" and see if other similar ASUS models have had same problem.

I have ASUS K-55A laptop and my Fn keys for volume work fine on Windows 10 Home. Vertical level appears on left side of laptop screen.
