This dlss mod tutorial for Gamepass Starfield just caused my game to crash on launch, any advice?

I am talking about this tutorial here:

I followed every step, I downloade a version above 2.x because i have an rtx 4060 graphics card
But ever since then the game just keeps crashing.does anyone have advice on this? Why is modding so annoyingly difficult on gamepass....
