You could go a different route and just pass it in when creating the widget from code.

MyUserWidget.h

// Fill out your copyright notice in the Description page of Project Settings.

#pragma once

#include "CoreMinimal.h"
#include "Blueprint/UserWidget.h"
#include "MyUserWidget.generated.h"

/**
 * 
 */
UCLASS()
class BALLROLL_API UMyUserWidget : public UUserWidget
{
	GENERATED_BODY()

public:
		
	UPROPERTY(BlueprintReadWrite, Category = "Default", meta = (ExposeOnSpawn = "true"))
		class AMyHUD* Hud;
};

MyUserWidget.cpp is empty

MyHUD.h

// Fill out your copyright notice in the Description page of Project Settings.

#pragma once

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

/**

UCLASS()
class BALLROLL_API AMyHUD : public AHUD
{
	GENERATED_BODY()
	AMyHUD(const FObjectInitializer& ObjectInitializer);
		
};

MyHUD.cpp

// Fill out your copyright notice in the Description page of Project Settings.


#include "MyHUD.h"
#include "MyUserWidget.h"
#include "Engine/World.h"

AMyHUD::AMyHUD(const FObjectInitializer& ObjectInitializer)// : Super(ObjectInitializer)
{
	
	UMyUserWidget* userW = CreateWidget<UMyUserWidget>(GetWorld(), UMyUserWidget::StaticClass(), "Widget");
	if (userW) {
		userW->Hud = this;
		userW->AddToViewport();
	}
