Editor crashes when Particle System Prewarm property is enabled and Sub-Emitter has a Trigger property set to Kill or Callback

Visual Effects - Legacy


How to reproduce:
1. Open the user's attached "" project
2. Open the "MainScene" Scene
3. Expand the "GameObject" GameObject in the Hierarchy window
4. Select the "PS_Root" GameObject in the Hierarchy window

Expected result: Particle System is displayed in the Scene view
Actual result: Editor crashes

Reproducible with: 2020.2.0a14, 2020.2.2f1, 2021.1.0b2, 2021.2.0a1
Not reproducible with: 2018.4.30f1, 2019.4.18f1, 2020.1.17f1, 2020.2.0a13

- To see what properties does the Particle System contain, disable the "GameObject" GameObject to avoid the Editor crash
- The issue is reproducible when the parent Particle System has the Preward property enabled
- The issue is reproducible with the Inside, Outside, Enter, Exit Trigger
