  1. Build Linux using make ShaderCompileWorker UnrealLightmass UnrealPak UnrealEditor
  2. Run Linux using ./Engine/Binaries/Linux/UnrealEditor
  3. Select Game in the Project Browser

EXPECTED:

The user is able to select an existing project or create a new project in the Project Browser

RESULT:

The Project Browser is unresponsive and the engine crashes
