Reproduction steps:
1. Open the attached user's project and "SampleScene" scene
2. Enter play mode, then press ESC and exit the play mode

Expected result: Editor leaves the play mode
Actual result: Editor crashes

Reproducible with: 2019.4.25f1, 2020.3.5f1, 2021.1.4f1, 2021.2.0a14
Could not test with: 2018.4.34f1 (compiler errors)

Notes: Does no longer reproduce when setting ScoutShip -> ShipBody -> Rigidbody -> Collision Detection to "Discrete"
