Starting a new game on my win system AMD-6300 takes about 8 seconds. Game has a very bad logic here and uses static time expensive code in grafic building objects. If your OS decides to kill the game process before it is finished, this could be one reason. You can also try to launch HOS and then immediately bring HOS to background by opening other app. This allows HOS to work the time consuming logic without the need to build the grafic. I used this on android emulators to avoid the 5 seconds "android app not responding timeout". But at some point there is another timeout killing "hanging" apps.
You can look bugreport about 332 days ago. There was the dialog to enclose this problem.
