Adding Instances to a Hierarchical Instanced Static Mesh causes crash

Adding Instances to the Hierarchical Instanced Static Mesh Component on BeginPlay causes the Editor to crash.

Tested in 4.19.2 (CL - 4033788), 4.20.1 (CL - 4229980), 4.21(CL - 4235929)

1. Download attached project
2. Move the Actor_BP Blueprint to the scene
3. PIE

Expected: 10 Instanced Static Meshes would be created on Begin Play

Result: The Editor hangs and then crashes

Assertion failed: IsRotationNormalized() [Link Removed] [Line: 1252]
