How to fix custom scaling issue on Asus ROG Strix G18 with Windows 11?

 
I have an Asus ROG Strix G18 (G814JZ) laptop with Windows 11 installed. I want to use the custom scaling option to adjust the size of text, apps, and other items on my screen. However, whenever I enter a custom value and apply the changes, the scaling reverts back to the previous preset value after a few seconds. This happens regardless of the custom value I enter. I have tried reformatting my laptop and getting a new one, but the problem persists. What could be the cause of this issue and how can I solve it?
