Description

Making a Blueprint instance of the AWorldSettings class, then saving/compiling instance

Tested in 4.20.3 (CL - 4369336), 4.21.2 (CL - 4753647), 4.22 (CL - 4958363)

Steps to Reproduce
  1. Create a Blank C++ project
  2. Create a custom class that derives from AWorldSettings named MyWorldSettings
    • Note you'll need to make the class Blueprintable.
  3. Compile
  4. Create a Blueprint from MyWorldSettings
  5. Compile or save the Blueprint

Expected: The Blueprint compiles and updates

Result: The Editor crashes
