Bro, the same thing happens to me, unlike you, I open the game for at least 5 minutes and the screen freezes and then says "not responding" and closes. That happened to me in the new update because when they released the game it was working great and now I can't even play without it closing (I'm a 64-bit game). Greetings from Venezuela.

check that your antivirus is not removing any game files. Next, your profile settings may be corrupted - you can reset them by deleting the Documents/Aottg2 folder and restarting the game. This can also be caused by OneDrive not allowing access to your Documents folder - you should exclude the OneDrive/Documents/Aottg2 folder from onedrive, or disable onedrive sync.
