When creating a subclass of World Settings, attempting to use the in-editor compile button to compile the code causes the editor to crash.
Found in 4.11 Preview 4. Reproduced in 4.10.2 binary and Main CL 2848314
1. Create a new blank C++ project
2. Create a subclass of World Settings
3. Go to Edit->Project Settings->General and change the World Settings to the new class you just created
4. Close the editor
5. Compile the project in Visual Studio
6. Open the editor
7. Create a UPROPERTY variable (I used a float)
8. Navigate to the editor and use the in-editor compile button
Result: Editor crashes
Expected: No crash would occur

When I open UE4 4.24.3 it appears that. Does anyone know how to solve?
