5.4.4 Can't Build Gameplay Ability System projects

Hello,
If I start an empty c++ project and add a GameplayAbilityComponent, or AttributeSet in c++ I get the following build error:

I’ve run the same test on 5.3 and 5.4.3, the steps are

  • Create a new C++ project
  • Turn on the Gameplay Abilities Plugin
  • Restart
  • In Unreal, Tools > New C++ Class
  • In the dialog create either a AbilitySystemComponent or AttributeSet
    This works in all Unreal version accept the most recent. Any help would be greatly appreciated.
