Reproduction steps:
1. Open the attached “crash_IN-61152.zip“ project
2. Open the “/Assets/Scenes/MainScene.unity“
3. Select the “Particle System“ GameObject
4. In the Inspector, the “Particle System“ Component, enable the “Trails“ module and “Generate Lighting Data“ property
5. Observe the crash
Reproduced with: 2022.3.11f1, 2022.3.15f1, 2023.2.4f1, 2023.3.0a18
Not reproduced with: 2021.3.33f1, 2022.3.10f1
Reproduced on: Windows 10 (22H2)
Not reproduced on: No other environments tested
Notes:
- Not possible to check if the issue is reproducible in Player as it’s not possible to modify the “Generate Lighting Data“ property dynamically
- The reproduction is almost consistent, so if enabling the “Generate Lighting Data“ property doesn’t crash the Editor immediately, wait for a few seconds or disable and enable the property again
