This article will dissect why this happens, where it comes from, and, most importantly, how to exorcise this ghost from your racing rig. First, it is crucial to understand what the error message isn't telling you. "SIM HAS CRASHED" is a generic exception handler. It is the game’s way of throwing its hands in the air and saying, "Something went wrong, but I don’t know what."
