Using HISM with Density Scaling enabled throws an Ensure when Foliage Quality is lowered

Using HISM with Density Scaling enabled throws an Ensure when Foliage Quality is lowered.

1. Open any project
2. Create a Public C++ class based on Actor named 'FooActor'
3. In the .h file:

   • UCLASS(Blueprintable)
     class AFooActor : public AActor
     {
        GENERATED_BODY()
        
     public:
        
        AFooActor(const FObjectInitializer& ObjectInitializer);
     
        UPROPERTY(VisibleAnywhere)
        UHierarchicalInstancedStaticMeshComponent* HISM;
     };

1. In the .cpp:
   • Add this code in the constructor

     AFooActor::AFooActor(const FObjectInitializer& ObjectInitializer)
        : Super(ObjectInitializer)
     {
        HISM = CreateDefaultSubobject<UHierarchicalInstancedStaticMeshComponent>("HISM"); 
        HISM->bEnableDensityScaling = true; 
     }

1. In the Editor navigate to the C++ classes in the content browser
2. Create a BP based off of FooActor
3. In the Blueprint select the HISM Component
4. In the Details Panel:
   • Search for 'Static Mesh' add a Cone or any mesh
   • Search for 'Instances' then in the Instances Array add 3 elements
   • Compile, save, and close the blueprint
5. Place the Blueprint Actor in the world
6. Near the top right corner of the editor select Settings(cog symbol)/Engine Scalability
7. Set Foliage Quality to Low

Expected Results:
Foliage quality is changed to low.

Actual Results:
Editor crashes with an Ensure Condition
