Windows 10: Can't change my laptop's brightness anymore

brightness is always high and the brightness bar is grayed out. I did search automatically for drivers in the device manger for my display adapters but it says "the best drivers for your device is already installed". what else should I look for to solve this issue.

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! -

If you are using a desktop, check if the brightness of the PC can be adjusted manually using the buttons located at the sides/bottom of the monitor. If you are using a laptop, check if you are able to adjust the brightness of the PC manually by using
