MissingReferenceException is thrown in the Play mode

Scripting

-

How to reproduce:
1. Open the attached repo-812099.zip project
2. Enter the Play mode

Expected: no errors in the Console window

Actual: Twoo errors are printed in the Console window:
- MissingReferenceException: The object of type 'DockArea' has been destroyed but you are still trying to access it.
- Failed to load window layout: System.ArgumentException: Window layout at '/Users/unity/Documents/PS/EditorMisc/test.wlt' could not be loaded.

MissingReferenceException reproducible with: 2019.1.0a10, 2019.1.14f1, 2019.2.21f1, 2019.3.14f1, 2020.1.0b9, 2020.2.0a11

Not reproducible with: 2018.4.23f1, 2019.1.0a9

  1. Resolution Note (2020.2.X):

    Unfortunately, the user code is switching layout while entering play mode which destroy and recreate new windows that register to EditorApplication.playModeStateChanged and at this time their view is not fully created causing many issue null ref issues. The user best options is to delay the layout change once the system has fully enter playmode.
