Rockstar launcher won't launch

[i do crack]

I've been trying for hours now without a fix. I bought an OLED Steam deck and as much as I'm happy with my purchase, it appears that Red Dead Redemption 2 won't launch. I have tried deleting launcher files, reinstalling, manually installing rockstar with no luck. Anyone has any other fix? Other than reinstalling launcher all over again? Because it seems like it won't work for me.
EDIT: It worked flawlessly on LCD steam deck.
