Sorry, I completely missed your reply.
I was simply trying to open a new map and was told by some UE4 programmers to use the code above. Since it caused the crash, I am using this instead and it works just fine:
UGameplayStatics::OpenLevel((UObject*) GetGameInstance(), FName(TEXT("MAP_Verran")), TEXT("listen"));
Since I have a work around, I won't bother you guys with a support ticket.
