What operating system are you using? Did you try right-click run as admin ? Do you see any kind of error?
Mine is Windows 10 and i did try to run it as admin, however a popup says that a "fatal crash" happend
Strange, I try on different Windows operating systems and it does not crash. Do you have Mac or Linux, I can create a build for those OS if you like.
I know what is happening, you have a custom build of Unreal Engine? If that's so, try a computer that does not have UE installed. That should fix the problem.
