Note:
Editor may randomly crash when moving/docking/closing/reopening Player Settings window, moving it to the secondary monitor, or on editor launch if Player Settings window opens by default

Only reproduced with the Player Settings window
Editor will occasionally crash immediately on launch if Player Settings window saved in editor layout and opens on launch
