The default settings in Project Settings - VFX start off without any compute shaders assignments. (new in 19.3 / 7.0.0?)
Manually assigning them and resetting the settings causes Unity to crash if a VFX is present in the scene.

Repro steps:
1. Open CrashScene from the attached project
2. Make sure the VFX is playing in the scene
3. Go to Project Settings - VFX
4. Click Reset from the gear icon
5. Unity crashes

Note:
- Should not crash
- Besides the crash, the compute shader settings should not start off empty, as there are no error messages to communicate why particles are not appearing
- A console warning should be added if the compute shaders are not set, with a helpful nudge as to where they might be found (Visual Effect Graph/Shaders).
