My gaming laptop lost LED lights and the functionality to adjust performance! (And trying to get Armoury Crate back!) How do I get it back?

I own an ASUS TUF Gaming F15 laptop, I got it for my birthday this year. After a BIOS Update in June (I think), I lost access to the LED lights on my keyboard (after months of finding solutions, I hope I came to the right place) and have no idea how to get it back. When I press FN + keyboard up, down, left or right, it does nothing physically even though the display saying I did it shows up. Now I lost the functionality to adjust performance after I accidentally uninstalled Armoury Crate in an attempt to get it updated. (I wish I never uninstalled it in the first place and left it as is.) Either an update or me uninstalling AC caused my laptop boot up to the user screen now takes me 6 minutes to get there. It used to be instant, what happened? I have tried time and time again to get Armoury Crate back, every time I install it, I get no restart prompt but I do anyways, having to wait another 6 minutes and you know what happens when I try to open it? It hangs for a brief moment and will not open no matter what I do. Any help would be greatly appreciated!
