The Fatal Error: Understanding and Fixing "Null CoreErrorsOpen Failed" in Mortal Kombat
For PC gamers, few things are as frustrating as anticipating the visceral combat of Mortal Kombat only to be met with a black screen and a cryptic error message before the game even launches. One of the most persistent and confusing errors plaguing players of Mortal Kombat 1 (MK1) and Mortal Kombat 11 (MK11) is the "Null CoreErrorsOpen Failed" crash.
This error typically appears at launch, before the game even shows the logos, or crashes immediately after the splash screen. It is not a standard Windows error; it’s an internal Unreal Engine 3 or 4 error (depending on the game) related to how the game reads its core configuration files. null coreerrorsopen failed mortal kombat new
