I started my computer as usual. But when I started RPH it took a few seconds and then a message popped up saying, "unable to launch game, please try reinstalling the game." and so I tried again, but same thing happened. I then tried reinstalling lspdfr to see if that was the issue, but the issue seems to be that Gta 5 can't start at all, not even without lspdfr/rph. And so i tried veryfing the game files but nothing out of the ordinary was found, i unstalled the game and then reinstalled it, but still nothing works. I have tried to run RPH as an adiminstrator and GTA aswell, but it just doesn't work. I also uninstalled rockstar games launcher and SDK and installed (I did that twice), I've updated my graphics driver so that it's up to date, my windows has no update available, no viruses is to be found, but the issue still persists. I've tried over 10 youtube tutorials where people have the same issue, and while it fixes it for them it just doesnt do anything for me.
I know it seems impossible to solve but if anyone has experienced this before, please tell me how to fix it.
