Crash on Check Always Create Physics State on Simulated Skeletal Mesh

When you place a Skeletal Mesh using a Simulated Physics Asset into a Blueprint, check Always create a Physics State and Save BP, crash.

[Link Removed]

Also reproduced in Main Promotable-CL-2599540

UPDATE- from Lina,

For me, it crashed when I change the state of the flag. But at the end same callstack . My callstack is below.
I'm not sure why Simulated root matters in this case. [Image Removed]

---------------------------------------------------

1. Open QAGame Editor
2. Open PhysicsAsset'/Game/QA_Assets/AI/Character/HeroTPP_Physics.HeroTPP_Physics'
3. Select the Root Bone
4. Set Physics Type to Simulated.
5. Save Physics Asset
6. Create a New Actor Blueprint
7. Add SkeletalMesh'/Game/QA_Assets/AI/Character/HeroTPP.HeroTPP' to the BP to current SceneComponent
8. Under Collision set Always Create Physics to true.

RESULTS: CRASH

EXPECTED: No CRASH
