I create a SpineCharacterClass and then create a bpclass, when I compile the bp twice, just crash
Here is the code

UCLASS()
class SPINEPLUGIN_API ASpineCharacter : public ACharacter
{
	GENERATED_UCLASS_BODY()

public:

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;

private:

	UPROPERTY(Category = Character, VisibleAnywhere, BlueprintReadOnly, meta = (AllowPrivateAccess = "true"))
	TObjectPtr<USpineSkeletonAnimationComponent> SkeletonAnimation;

	UPROPERTY(Category = Character, VisibleAnywhere, BlueprintReadOnly, meta = (AllowPrivateAccess = "true"))
	TObjectPtr<USpineSkeletonRendererComponent> SkeletonRenderer;

};`

`ASpineCharacter::ASpineCharacter(const FObjectInitializer& ObjectInitializer)
	: Super(ObjectInitializer.DoNotCreateDefaultSubobject(ACharacter::MeshComponentName))
{
 	// Set this character to call Tick() every frame.  You can turn this off to improve performance if you don't need it.
	PrimaryActorTick.bCanEverTick = true;

	SkeletonAnimation = CreateDefaultSubobject<USpineSkeletonAnimationComponent>(TEXT("SkeletonAnimation"));
	SkeletonRenderer = CreateDefaultSubobject<USpineSkeletonRendererComponent>(TEXT("SkeletonRenderer"));

}
