Resolution keeps resetting back to native

Can someone help me because my native resolution is 1080p, but i changed the game resolution to 1440p to use DLDSR. It works, but when I close the game and then open it again, every setting seems good and the resolution says it's 1440p but its clearly in 1080p because MSI Afterburner overlay is not smaller, and it looks worse and blurry beacuse it's using DLSS but the resolution is not higher than the native one, so not using DSR. Also I checked the WindowsClient folder and it's read-only, in GameUserSettings it says clearly that the resolution the game needs to run is 1440p. I know i can change it everytime i open the game and it's done, but i wanna solve this issue and it's really frustating.
