can you give plaese me suggestions on how to fix this issue.
thanks in advance

MenuHUD.h

#include "CoreMinimal.h"
#include "GameFramework/HUD.h"
#include "MenuHUD.generated.h"

UCLASS()
class REDIALMENU_API AMenuHUD : public AHUD
 {
     GENERATED_BODY()

protected: 

     TSharedPtr<class SMenuWidget> MenuWidget;
     TSharedPtr<class SMenuWidget> MenuWidgetContainer;

     virtual void BeginPlay() override;
};

MenuHUD.cpp

#include "MenuHUD.h"
#include "SMenuWidget.h"
#include "Widgets/SWeakWidget.h"
#include "Engine/Engine.h"


 void AMenuHUD::BeginPlay()
 {
     Super::BeginPlay();

     if (GEngine && GEngine->GameViewport)
     {
	     MenuWidget = SNew(SMenuWidget).OwningHUD(this);
	     GEngine->GameViewport->AddViewportWidgetContent(SAssignNew(MenuWidgetContainer, 
         SWeakWidget).PossiblyNullContent(MenuWidget.ToSharedRef()));
	
     }
 }

SMenuWidget.h

     virtual bool SupportsKeyboardFocus() const override { return true; };
 };

Same error here.
Im trying use an Array of Enums, and cant create a getter function.

Try forward-declaring your SMenuWidget class outside of the class declaration scope instead of within, like so :

#include "CoreMinimal.h"
#include "GameFramework/HUD.h"
#include "MenuHUD.generated.h"

class SMenuWidget;

UCLASS()
class REDIALMENU_API AMenuHUD : public AHUD
 {
     GENERATED_BODY()

protected: 

     TSharedPtr<SMenuWidget> MenuWidget;
     TSharedPtr<SMenuWidget> MenuWidgetContainer;

     virtual void BeginPlay() override;
};
