Regression
Yes
VFX Graph effect instance stops rendering when a second instance of the same effect starts 2 frames later
Reproduction steps:
1. Open the attached “IL2CPP_Crash.zip” Project
2. Open the “VFXScene” scene (Assets > VFXGraphBug)
3. Enter the Play mode
4. Select the “Test” GameObject in the Hierarchy
5. In the Inspector toggle the “Play BB Sequentially” property at least a few times
Expected result: Two instances of the same effect are visible
Actual result: One of the effects stops playing immediately, leaving only one effect visible
Reproducible with: 2022.2.0b4, 2022.3.24f1, 2023.2.18f1, 2023.3.0a19
Not reproducible with: 2021.3.37f1, 2022.2.0b3, 6000.0.0b14
Fixed in: 2023.3.0b1
Reproducible on: Windows 11
Not reproducible on: No other environment tested
Notes:
- In between toggling the “Play BB Sequentially” property, make sure to wait for the effects to be inactive before toggling it again, for the best reproduction results. The issue also usually reproduces only after the toggle has been toggled twice
- The gizmo of the stopped effect is still shown after the effect has stopped being rendered
- Upgrading from 2021.3 (or from any working version) to any other version (except for beta and some alfa versions), makes the issue not reproducible on versions where it reproduced when upgrading from 2022.3.24f1

Experiencing this issue on 2022.3.13f1 as well. I had to disable instancing on the effect to get around this issue. I also noticed, if you disable and re-enable the GameObject of first effect that stopped rendering in play mode, it starts rendering again and both effects render properly.
This appears to be related to instancing. With instancing disabled on the VFX Graph, this does not happen for me.
