Gameplay Ability System Plugin

Would love some help Thank You

  • Unreal Engine version: 5.5.4 and 5.4.4.
  • The exact file and location: E:\...\Engine\Plugins\Runtime\GameplayAbilities\Source\GameplayAbilities\Public\GameplayEffectTypes.h.
  • The specific corruption: The FGameplayEffectSpec struct is missing SetByCallerMagnitudes, GetSetByCallerMagnitude, and HasSetByCallerMagnitude.
  • All troubleshooting steps taken (and their results):
    • Multiple “Verify” attempts on UE 5.5.4.
    • Multiple full uninstalls and reinstalls of UE 5.5.4 on different drives.
    • A completely fresh installation of UE 5.4.4 on a different drive.
    • Confirm that the GameplayEffectTypes.h file is corrupted in all of these separate installations.
    • I tried deleting project Binaries/Intermediate/Saved and regenerating project files.
    • I tried creating new C++ projects and they also fail with the same error.

Duplicate of Corrupted File

Will reply in other post as it contains more info. If you want to move a post up in the forum list, you can post a reply to it instead of creating a new post.
