check your resolution, thats what it was for me, make sure its 720p or 1080, not sure for 1440p, 4k, but mine was on 690p and i just changed it to 720p and it worked
I had my screen resolution at 2048x1080 and the game would crash at the splash screen. I changed it to 1920x1080 and it started up fine and working normally now.
what worked for me was running the game from the root directory. find the ACU.exe and double click it. didn't have to do any other weird work around. I hope it helps.
