I have exact same problem too.
We paid too much money for such a foolish problem.
The game (all forza games) do not launch on windows 10, just splash screen and then after 2 seconds the splash screen goes away and game does not launch.
We need an immediate solution.
I also have this problem. I click the game and it’s just the splash screen with the senna but the game never actually launches it just stays on that screen for about 40 seconds and then closes. I had forza horizon 3 on my old computer and it worked but when I got this new computer horizon 3 never opened. I thought horizon 4 would have fixed this problem seeing as the demo worked fine for me. This is a ridiculous issue as I paid $130 for this game and all of it’s DLC.
if you have an external monitor then that might be the problem if running it on a laptop, just unplug it when launching and plug it back in when it has luanched
I am having the same issue with Horizon 4. Just the splash screen then it freezes for a few minutes then disappears, game never starts. Seems like 100+ dollars is quite a bit to spend on a Forza Horizon 4 picture that disappears after a few minutes and takes 64gb to download. This needs fixed immediately.
When I first encounter this problem, I was setting video options that caused game reboot. But the game never launch again.
Try to reset app by right clicking on Forza Horizon 4 > More > App Settings > “Terminate” then “Reset”.
I hope that will help.
I was having the same issue. With MSI afterburner running, the damn game gets to the splash screen and dies. I closed MSI afterburner and it immediately runs.
