Unreal Engine Issues and Bug Tracker (UE-75632)

Description

Ensures trigger when playing in the ChaosExamples_fracture map in the ChaosDestructionDemo project.

The ensures seem to happen during different parts. A couple occurrences were when I triggered the 1.5 - Multiple Fracture Types and Layers demo, and one occurrence was when I exited PIE (though that may have been a timing thing)

Steps to Reproduce

Open ChaosDestructionDemo in editor.
Open ChaosExamples_fracture.
Play in viewport.
Trigger all the fracture examples.

RESULT

Ensures occur
