I'm using the paid version of DSX on steam + GTA on steam but even after following all the steps in the order of the video when I open GTA the default shortcut F10 doesn't work (nothing opens on the screen, even changing the shortcut it still doesn't open).

I have a “clean” installation of GTA, without any other mods.

How can I adjust it?
