Crash in CalculateSurfaceArea when enabling "Contribute Global Illumination" on a Mesh that is created by a compute shader

Mesh

-

Reproduction steps:
1. Open the user's attached project
2. Enter play mode in scene "NoiseField"
3. Enable "Contribute Global Illumination" on object "Visualizer"

Expected result: "Contribute Global Illumination" is enabled
Actual result: Editor crashes

Reproducible with: 2021.2.0a18, 2021.2.0b1
Could not test with: 2018.4, 2019.4, 2020.3, 2021.1, 2021.2.0a17 (Errors in console, can't enter play mode)

Notes:
Seems to be related to the new Mesh API introduced in 2021.2.0a18
