Unity freezes on LightmapEditorSettings:HasZeroAreaMesh(Renderer) when selecting certain Game Objects in the Scene View

Global Illumination


How to reproduce:
1. Open the user submitted-project ("crossy")
2. Open the Scene View and Enter Play mode
3. In the Scene View, select any of the grass block objects

Expected result: The block objects are selected and its contents are visible in the inspector window
Actual result: Unity freezes and continuously leaks memory

Reproduced in: 2019.1.0a6, 2018.3.0b8, 2018.2.14f1, 2018.1.9f2
Couldn't test with: 2017.4.14f1 (The project completely breaks)

- Disabling "Baked Global Illumination" in the Lighting settings Window stops the freezing
- Opening Lighting window before launching the scene fixes the issue.
- Reloading the scene doesn't fix the bug.
