Crash on WriteParticleLineVertex when particle systems are rendered in a specific project
Reproduction steps:
1. Open the attached project "CrashRepro"
2. Enter Play mode
3. Click the “continue” button twice
4. Click on the purple button in the middle
5. Click the “Workshop“ button
6. Click the “back” button and the "exit” button
7. Repeat from step 4
Expected result: UI windows are switched without issues
Actual result: Editor crashes
Reproducible with: 2022.3.61f1, 6000.0.47f1, 6000.1.0f1, 6000.2.0a9
Reproducible on: Windows 11
Not reproducible on: No other environment tested
Notes:
Inconsistent reproduction usually takes a few minutes to crash on 2022.3.
6000.x and above, the crash seems to become even more inconsistent, but I could reproduce it by doing all the steps up to 5 and leaving it in the background for around an hour.
