play 누르면 에디터가 꺼지고 이런 에러 메세지가 뜨고,

ArenaBattle 프로젝트를 다시 시작하면 이런 에러 메세지가 뜹니다.

// Input
	static ConstructorHelpers::FObjectFinder<UInputMappingContext> InputMappingContextRef(TEXT("/Script/EnhancedInput.InputMappingContext'/Game/ArenaBattle/Input/IMC_Default.IMC_Default'"));
	if (nullptr != InputMappingContextRef.Object)
	{
		DefaultMappingContext = InputMappingContextRef.Object;
	}

	static ConstructorHelpers::FObjectFinder<UInputAction> InputActionMoveRef(TEXT("/Script/EnhancedInput.InputAction'/Game/ArenaBattle/Input/Actions/IA_Move.IA_Move'"));

나눠주신 소스코드를 그대로 복붙했는데도, 왜 이런 건지 감이 안오네요.

이건 visual studio에서 ctrl + f5 빌드 했을때, 나오는 에러 메세지 입니다. 참조를 못하는가 싶어서

https://bangp.tistory.com/36 이 링크에 나온 내용처럼 ArenaBattle 속성에 "포함검색 경로"란에 "C:\Program Files\Epic Games\UE_5.1\Engine\Intermediate\Build\Win64\UnrealEditor\Inc" 이런 경로도 추가해 봤지만 해결하지 못했습니다. 어떤 문제인지 알려주시면 감사하겠습니다.
