When a new game is released, there are still many bugs in it. And those bugs might cause the game crash issues. So developers keep updating the games to fix the bugs and improve the gaming performance.

So if there is a patch available, download and install it, then run the game again to check if the problem is solved. If it isn’t, or there is no new patch available, then move on to Fix 7.

Fix 7: Verify the integrity of game files
