The BlueprintCDO is nullptr.
How can I fix it?

AGameMode_InGame::AGameMode_InGame(const FObjectInitializer& ObjectInitializer)
	: Super(ObjectInitializer)
{
	if (!ItemDataLibrary)
	{
		ItemDataLibrary = UObjectLibrary::CreateLibrary(UObject::StaticClass(), false, false);
		ItemDataLibrary->AddToRoot();
	}
	ItemDataLibrary->LoadAssetDataFromPath(TEXT("/Game/Items")); // -> changed to /Game/Items/Textures
	const bool bFullyLoad = true;
	if (bFullyLoad)
	{
		ItemDataLibrary->LoadAssetsFromAssetData();
	}
}

“/Game/Items” folder contains some blueprint classes.
I solved the problem by changing the path(LoadAssetDataFromPath()).

Hey Johnapoor-

Is this code in a custom class for your project or an engine class? If this is an engine class, which class are getting this from and how are you accessing this code? Also, please include the logs from packaging the project for additional information.
