Brightness not adjusting ASUS TUF A15

I have just bought this laptop yesterday, I know about updating the Display Adapter drivers and it doesn't fix it, nor disabling and enabling it, even resetting the laptop doesn't work. Also I know that it is not a driver problem because if it was the resolution would be wacky and big (as windows default) and also night light won't be on if you tried to but both are working, actually everything is working except the brightness. I can pull it down and up but it doesn't change at all even on the Fn buttons. I have updated all of the drivers to its latest and it doesn't work at all. Anyone with a fix? My eyes hurt so much because of it and I can't work properly. I was thinking if it was the Armory Crate that affects it? I can't be sure but I can't find other brightness options on other apps except the windows settings one and it doesn't work
