Crash on entering Play mode when a script is calling NavMeshSurface.UpdateNavMesh()

AI

-

How to reproduce:
1. Open the attached project named "NavMeshTest.zip"
2. Open the Game Scene located in Assets/Src/Scenes/Game
3. Enter Play mode. If the crash does not occur, exit and enter the Play mode a few times

Expected results: The Scene is loaded and Editor enters into Play mode
Actual results: Editor crashes when entering Play mode

Reproducible with: 2019.4.20f1, 2020.1.17f1, 2020.2.5f1, 2021.1.0b7, 2021.2.0a4
Could not test with: 2018.4.30f1(Project breaks on downgrade)

Notes:
1. Crash usually occurs when trying to enter the Play mode for the second time
2. If line 12 in Map.cs is removed, the crash does no longer occur
3. Start(), FixedUpdate() and Update() methods were tested for the UpdateNavMesh call. The issue would reproduce in all test cases
