Regression
Yes
Crash on ParticleSystem::EndUpdateAll() when exiting Play mode while a Particle System is simulating
How to reproduce:
1. Open the attached project '1206498.zip'
2. Open 'Main Menu (Console)' scene
3. Enter Play mode
4. Exit it
-- observe the crash
Reproducible with: 2019.3.0b8, 2019.3.0f5, 2020.1.0a9, 2020.1.0a18
Not reproducible with: 2018.4, 2019.2, 2019.3.0b7, 2020.1.0a8
First few lines of the stack trace:
#0 0x005566b764287e in ParticleSystem::EndUpdateAll()
#1 0x005566b764314d in ParticleSystem::InitializeClass()::PostLateUpdateParticleSystemEndUpdateAllRegistrator::Forward()
#2 0x005566ba0133fe in ExecutePlayerLoop(NativePlayerLoopSystem*)
#3 0x005566ba01346a in ExecutePlayerLoop(NativePlayerLoopSystem*)
Note:
- In the UIParticleRenderer.cs script the Start() method starts simulating a Particle System for 10 seconds, to reproduce the crash you have to exit Play mode in that period

I can confirm this crash happens on Android Build using Unity 2019.3.0f5.

I just received this issue as well on updating to 2019.3.0f5. It is 100% reproduceable.

I'm still having this issue, Editor crashes in play mode
PostLateUpdateParticleSystemEndUpdateAllRegistrator
Seems to be related to the particles in my object pooling system.

I'm pretty sure I'm having this same bug without exiting play mode.
It's crashing sometimes for me when a particle system is destroyed while playing, and it happens in out-of-editor builds which makes it a higher priority issue than the initial report suggests.

The issue is caused when a system has a stop action and gets destroyed while it is culled.
We have a fix which will be available soon.
