Editor crashes: load game level to menu level/restarting the game multiple times

Hello,

I am working on the menu for my multiplayer project. When I load the level to the main menu multiple times (often two - sometimes three times), the editor get’s shut down and I get this error message:

When I try to debug the code, it sends me into the engine where it seems to try to create something in memory which it is not allowed to. I am using the Unreal source version from git hub. And tried to comment out everything from the code, so I only had this left for execution:

#include "GameInstance_ProjectTheseus.h"	
#include "GameFramework/PlayerController.h"
#include "GameFramework/GameMode.h"

#include "UObject/ConstructorHelpers.h"
#include "Blueprint/UserWidget.h"
#include "MenuSystem/UUW_Base_Menu.h"

UGameInstance_ProjectTheseus::UGameInstance_ProjectTheseus(const FObjectInitializer& ObjectInitializer)
{
 // TODO: Change from FClassFinder to something less prone to error
	ConstructorHelpers::FClassFinder<UUserWidget> MainMenuWBPClass(TEXT("/Game/MenuSystem/WBP_MainMenu"));
	ConstructorHelpers::FClassFinder<UUserWidget> InGameMenuWBPClass(TEXT("/Game/MenuSystem/WBP_InGameMenu"));
	if (!ensure(MainMenuWBPClass.Class != nullptr)) return;
	MainMenuClass = MainMenuWBPClass.Class;
	if (!ensure(InGameMenuWBPClass.Class != nullptr)) return;
	InGameMenuClass = InGameMenuWBPClass.Class;
}

void UGameInstance_ProjectTheseus::LoadMainMenu()
{
	// Create widget in viewport
	if (!ensure(MainMenuClass != nullptr)) return;
	MainMenu = CreateWidget<UUUW_Base_Menu>(this, MainMenuClass);
}

Does anyone have any suggestions?

The Exception error is thrown in ContainerAllocationPolicies.h at line 425

		ForAnyElementType()
			: Data(nullptr)

and reads as follows:

Exception thrown at 0x00007FFD2713118B (UE4Editor-CoreUObject.dll) in UE4Editor.exe: 0xC0000005: Access violation writing location 0x00007FFD1FA010C0.

Usually, when this happens there’s a pointer somewhere that is uninitialised and causes the crash.

Unreal doesn’t give much help when this happens so you need to go though your C++ code and ensure that all your code is checking for nulls being used.
