강의 내용 중 ABItemPotionData와 ABItemScrollItemData 클래스를 생성한 뒤 코드를 똑같이 입력하고 에디터 실행했더니 위 에러 메시지와 함께 에디터가 열리지 않고 있습니다.

DefaulGame.ini의 셋팅도 문제 없습니다.

ABItemBox.cpp 의 에셋 매니저에서 에셋을 불러올 때 배열이 비어있는 것 같습니다.

void AABItemBox::PostInitializeComponents()
{
    Super::PostInitializeComponents();

    UAssetManager& Manager = UAssetManager::Get();

    TArray<FPrimaryAssetId> Assets;
    Manager.GetPrimaryAssetIdList(TEXT("ABItemData"), Assets);
    ensure(0 < Assets.Num());

    int32 RandomIndex = FMath::RandRange(0, Assets.Num() - 1);
    FSoftObjectPtr AssetPtr(Manager.GetPrimaryAssetPath(Assets[RandomIndex]));
    if (AssetPtr.IsPending())
    {
        AssetPtr.LoadSynchronous();
    }
    Item = Cast<UABItemData>(AssetPtr.Get());
    ensure(Item);

    Trigger->OnComponentBeginOverlap.AddDynamic(this, &AABItemBox::OnOverlapBegin);

}

깃헙에 올려주신 코드와 비교해보았는데 다른 부분이 없어서 어느 것이 문제인지 알고 싶습니다.

에디터가 열리지 않아서 설정을 확인할 수 없습니다。

추가로, 올려주신 프로젝트를 다운받아 실행했더니 똑같은 문제가 발생했습니다..
