Editor crashes on BaseRenderer::FlattenCustomProps when adding materials in the Mesh Renderer after SetPropertyBlock was called

Mesh Renderer


To reproduce:
1. Open the user's attached "" project
2. Load the "test" scene
3. Select the "Sphere" GameObject in the Hierarchy window
4. Click on the "Set Color Now" checkbox in the Inspector window
5. Change the size of Materials in the Mesh Renderer component
--Observe the crash

Reproducible with: 2018.4.28f1, 2019.4.13f1, 2020.1.10f1, 2020.2.0b8, 2021.1.0a2

Could not test with 2017.4.32f1 because there is no SetPropertyBlock(MaterialPropertyBlock properties, int materialIndex) method

Note: calling SetPropertyBlock(MaterialPropertyBlock properties) instead of SetPropertyBlock(MaterialPropertyBlock properties, int materialIndex) does not crash the Editor when changing Materials count in the Mesh Renderer
