When i try to open the game (administrator or not) the game wont boot up and closes again....
I'm not a mind reader, so I can't magically know what's causing the issue on your end. 😅
I tested the game on both my phone and PC, and everything works fine for me. So logically, something on your PC might be causing the problem. But what exactly? I have no way of knowing without more information.
What version of Windows are you using? Have you played other demanding games on this PC before, especially ones that require DirectX 12? What are your PC specs?
The more information you give me, the better my chances of figuring out what's wrong and fixing it! :)
