Yes, I found a solution and now I have back the sliders.
I think, this solution can be usefull for any rog model users.
I am explaining it step by step below;
1- Uninstal the armoury crate by using uninstal tool of armoury crate.
2- Instal the file that I shared below via a link. The file is a armoury crate service setup that I found from back up file a 2020 model g14 user on the internet.
https://s6.dosya.tc/server/tub807/ARMOURY_CRATE_SERVICE.rar.html"ArmouryCrateSetup" is the file that will be installed.
3- Instal the latest version of Armoury Crate normally from Asus Support Site.
4-Update the armoury crate from update center in armoury crate software and you need to see the update that I circled in the image below.
In the end, the GPU boost CPU limit sliders System Acoustics etc. must have came back.
I hope, it will help you.
