Details panel of native component missing in Blueprint

[juayhee (jhjh)]

Hello,
I am facing an issue where I cannot see the details panel of my component. It would be greatly appreciated if anyone can help. I have outlined the steps I took to reproduce my issue and what I have tried so far below.

Issue

I have an AMyCharacter class that derives from ACharacter. I want to add a custom Ability Component to it - this class will be responsible for firing abilities from AMyCharacter.
This custom component is called UAbilityComponent and it derives from UActorComponent.

1. Adding AMyCharacter

2. Rider generated MyCharacter.h

#pragma once

#include "CoreMinimal.h"
#include "GameFramework/Character.h"
#include "MyCharacter.generated.h"

UCLASS(Blueprintable)
class MYGAME_API AMyCharacter : public ACharacter
{
	GENERATED_BODY()

public:
	// Sets default values for this character's properties
	AMyCharacter();

protected:
	// Called when the game starts or when spawned
	virtual void BeginPlay() override;

public:
	// Called every frame
	virtual void Tick(float DeltaTime) override;

	// Called to bind functionality to input
	virtual void SetupPlayerInputComponent(
		class UInputComponent* PlayerInputComponent) override;
};

3. Rider generated MyCharacter.cpp

#include "Test/MyCharacter.h"


// Sets default values
AMyCharacter::AMyCharacter()
{
	PrimaryActorTick.bCanEverTick = true;
}

// Called when the game starts or when spawned
void AMyCharacter::BeginPlay()
{
	Super::BeginPlay();
	
}

// Called every frame
void AMyCharacter::Tick(float DeltaTime)
{
	Super::Tick(DeltaTime);
}

// Called to bind functionality to input
void AMyCharacter::SetupPlayerInputComponent(
	UInputComponent* PlayerInputComponent)
{
	Super::SetupPlayerInputComponent(PlayerInputComponent);
}

I then create a child blueprint from AMyCharacter.

There is no issue so far.

Then, I introduced my UAbilitiesComponent.

1. AbilitiesComponent.h

#include "CoreMinimal.h"
#include "GameFramework/Character.h"
#include "AbilitiesComponent.generated.h"
UCLASS(meta=(BlueprintSpawnableComponent))
class MYGAME_API UAbilitiesComponent : public UActorComponent
{
	GENERATED_BODY()

public:
	UAbilitiesComponent();

	// Called every frame
	virtual void TickComponent(float DeltaTime, ELevelTick TickType,
	                           FActorComponentTickFunction*
	                           ThisTickFunction) override;

protected:
	// Called when the game starts
	virtual void BeginPlay() override;

    // Property for testing purposes
    UPROPERTY(EditAnywhere, BlueprintReadOnly)
    float TestFloat = 0;
};

2. UAbilitiesComponent.cpp

#include "AbilitiesComponent.h"


UAbilitiesComponent::UAbilitiesComponent()
{
}


// Called when the game starts
void UAbilitiesComponent::BeginPlay()
{
	Super::BeginPlay();
}


// Called every frame
void UAbilitiesComponent::TickComponent(float DeltaTime, ELevelTick TickType,
                                        FActorComponentTickFunction*
                                        ThisTickFunction)
{
	Super::TickComponent(DeltaTime, TickType, ThisTickFunction);
}

Finally, I introduce the UAbilitiesComponent into AMyCharacter via UPROPERTY.

1. Updated MyCharacter.h

#pragma once

#include "CoreMinimal.h"
#include "AbilitiesComponent.h"
#include "GameFramework/Character.h"
#include "MyCharacter.generated.h"

UCLASS(Blueprintable)
class MYGAME_API AMyCharacter : public ACharacter
{
	GENERATED_BODY()

public:
	// Sets default values for this character's properties
	AMyCharacter();

protected:
	// Called when the game starts or when spawned
	virtual void BeginPlay() override;

public:
	// Called every frame
	virtual void Tick(float DeltaTime) override;

	// Called to bind functionality to input
	virtual void SetupPlayerInputComponent(
		class UInputComponent* PlayerInputComponent) override;

	UPROPERTY(EditAnywhere, BlueprintReadWrite)
	TObjectPtr<UAbilitiesComponent> AbilitiesComponent;
};

2. Updated MyCharacter.cpp

#include "Test/MyCharacter.h"


// Sets default values
AMyCharacter::AMyCharacter()
{
	PrimaryActorTick.bCanEverTick = true;

	AbilitiesComponent = CreateDefaultSubobject<UAbilitiesComponent>(
		TEXT("Ability Component"));
}

// Called when the game starts or when spawned
void AMyCharacter::BeginPlay()
{
	Super::BeginPlay();
}

// Called every frame
void AMyCharacter::Tick(float DeltaTime)
{
	Super::Tick(DeltaTime);
}

// Called to bind functionality to input
void AMyCharacter::SetupPlayerInputComponent(
	UInputComponent* PlayerInputComponent)
{
	Super::SetupPlayerInputComponent(PlayerInputComponent);
}

Now, I close the editor, compile, and open BP_MyCharacter.
The details panel for the new component shows up as expected.

Next, I close the editor, then open it again.

The details panel is now gone.

Attempted Solutions

I have tried several solutions after searching on the forums, but none of them have helped. They are listed below:

1. In the class default constructor, change the name given to the component duringCreateDefaultSubobject<>()
   
   → Didn’t work. Details panel is still empty.

2. In AMyCharacter, change the variable name for the UAbilitiesComponent.
   
   → Didn’t work. Details panel is still empty.

3. Reparenting, then parenting back.
   

   
   
   
   
   
   → Works only once. After closing and opening the editor, the details panel is gone again.

4. Recreating the entire blueprint. Works only once. After closing and opening the editor, the details panel is gone again.

5. Deleting Intermediate and Saved folders and recompiling. Doesn’t work.

Any help would be greatly appreciated. If more information is needed please let me know so I can provide it.

Resolved - it was something to do with core redirect referencing assets that do not exist anymore. I deleted all core redirects in the engine settings .ini and fixed up any bad references myself. The details panel shows properly now.
