Enabling the experimental Unit Test Framework in a project results in the Editor crashing whenever that project is opened

A user decided to test the experimental Unit Test Framework plugin that was included with 4.11. The user discovered that the Editor will crash whenever opening a project that has this plugin enabled, and found a workaround to allow the Editor to open the project successfully.

1. Create a new Blueprint First Person project.
2. Open the Plugins window.
3. Enable the Unit Test Framework plugin.
   • Built-in -> Experimental
4. Restart the Editor when prompted.

RESULT:
The Editor will crash whenever it attempts to open the project.

EXPECTED:
The Editor opens the project normally.

WORKAROUND:
Locate the UnitTestFramework.uplugin file in the Engine/Plugins/Experimental/UnitTestFramework folder. Open the file for editing and change the LoadingPhase for the UnitTestFrameworkEditor module from Default to PostEngineInit. Rebuild the Engine with the new LoadingPhase set and the project will open successfully in the Editor.
