So Far Everything Crashes

Granted all I’ve tried so far is Final Fantasy XIII-2 and Killing Floor 2. When I run Final Fantasy XIII-2 with Infinity 2.0 it crashes either at the main menu when I hit “continue” or when I select a level to go to. When I play Killing Floor 2 It crashes after I run infinite health, ammo, and no reload the second I hit a zombie or sometimes just when I begin a match and activate the cheats.
