Loading screen tutorial not work

Hi. I want to show animated loading screen. Then I found loading screen tutorial and I try it. But it is not working can’t.
I edit my game Instance and set it to project setting’s instance. I checked break point is work. But it is not show anything. What am I miss?

Here is the my code and screen shot.

#include “GameInstanceEx.h”
#include “MoviePlayer.h”

void UGameInstanceEx::Init()
{
Super::Init();

FCoreUObjectDelegates::PreLoadMap.AddUObject(this, &UGameInstanceEx::BeginLoadingScreen);
FCoreUObjectDelegates::PostLoadMapWithWorld.AddUObject(this, &UGameInstanceEx::EndLoadingScreen);

}

void UGameInstanceEx::BeginLoadingScreen(const FString& in_levelName)
{
FLoadingScreenAttributes LoadingScreen;
LoadingScreen.bAutoCompleteWhenLoadingCompletes = true;
LoadingScreen.MoviePaths.Add(TEXT(“/Game/Movies/LoadingMovie.LoadingMovie”));
LoadingScreen.WidgetLoadingScreen = FLoadingScreenAttributes::NewTestLoadingScreenWidget();

	GetMoviePlayer()->SetupLoadingScreen(LoadingScreen);

}

void UGameInstanceEx::EndLoadingScreen(UWorld* in_loadedWorld)
{

}

As a bonus, the system requires no additional calls or setup from the user and is entirely self-contained. Loading a map via any means (other than PIE) will trigger the load visualization seamlessly.

you need run the game in stand alone mode
