Description

Reproduced 3/3 times, issue also occurs in //UE5/Release-5.0 - CL 20979098 Binary. Confirmed NOT a Regression.

Issue does not occur when user Simulates in level viewport, nor when geometry collection is initially set to enable physics without the beginplay cmd.

Steps to Reproduce
  1. Create a new actor BP
  2. Add a Geometry Collection component
  3. In Event Graph, drag off from BeginPlay
  4. Search and select "Set Simulate Physics(Geometry Collection)
  5. Compile
  6. Click the Simulation Button (The one next to Class Defaults, not the alt-S command)

Actual Result: Editor crashes immediately

Expected Result: Geometry Collection should "fall" infinitely in the Blueprint Viewport
