Hello, i wrote loading screen code like “ActionRPG” or “StrategyGame”, in standalone every thing is okay but in packeged project Stextblock is invisible.

TemplateGameInstanceBase.h :

#include "CoreMinimal.h"
#include "Engine/GameInstance.h"
#include "TemplateGameInstanceBase.generated.h"

UCLASS()
class TEMPLATE_API UTemplateGameInstanceBase : public UGameInstance
{
	GENERATED_BODY()

public:
	UFUNCTION(BlueprintCallable)
	void StartLoadingScreen(bool bPlayUntilStop, float PlayTime);

	UFUNCTION(BlueprintCallable)
	void StopLoadingScreen();
};

TemplateGameInstanceBase.cpp :

#include "TemplateGameInstanceBase.h"
#include "MoviePlayer.h"
#include "SMyWidget.h"
#include "SlateBasics.h"
#include "SlateExtras.h"

void UTemplateGameInstanceBase::StartLoadingScreen(bool bPlayUntilStop, float PlayTime)
{
	FLoadingScreenAttributes LoadingScreen;
	LoadingScreen.bAutoCompleteWhenLoadingCompletes = !bPlayUntilStop;
	LoadingScreen.bWaitForManualStop = bPlayUntilStop;
	LoadingScreen.bAllowEngineTick = bPlayUntilStop;
	LoadingScreen.MinimumLoadingScreenDisplayTime = PlayTime;
	LoadingScreen.WidgetLoadingScreen = SNew(SMyWidget);
	GetMoviePlayer()->SetupLoadingScreen(LoadingScreen);
}

void UTemplateGameInstanceBase::StopLoadingScreen()
{
	GetMoviePlayer()->StopMovie();
}

SMyWidget.h :

#include "CoreMinimal.h"
#include "Widgets/SCompoundWidget.h"

class TEMPLATE_API SMyWidget : public SCompoundWidget
{
public:
	SLATE_BEGIN_ARGS(SMyWidget)
	{}
	SLATE_ARGUMENT(TWeakObjectPtr<class AMyHUD>, HUDArg);
	SLATE_END_ARGS()

	void Construct(const FArguments& InArgs);
