Editor crashes with WorldCollision when Spawning Particles

Visual Effects - Legacy


How to reproduce:
1. Open the user's project
2. Open the "Scenes/MagicArcher" Scene
3. Enter the Play Mode
4. Open the Scene Window
5. Select all of the grenades on the table
6. Lift them up and drop them

Expected result: Editor does not crash
Actual result: Editor crashes with (Unity) WorldCollision

Reproducible with 2019.1.0b3, 2019.1.4f1, 2019.2.0a4
Not reproducible with 2018.4.1f1, 2019.1.0b2

Could not attempt to reproduce on newer versions than 2019.2.0a4 due compiler errors

    Also has same issue. It crashes both in game and in editor. It worked fine in 2019.1.8 and then checked in 2019.2, 2019.1.10, 2019.1.12, 2019.1.14 - it fails.

    I can assume this is what is crashing my project as well, as I narrowed it down to a prefab with a particle effect that would crash the scene on opening it. I also saw this happen since 2019.1.9.
