I found a temporary solution for the red cross failure in Gather Text, working as of 7/25/2025 UE5.6 – you’ll need a previous version of Unreal installed, in my case UE5.5 worked.
- Navigate to C:/Program Files/Epic Games/UE_5.5/Engine/Content/Localization/
- Copy both the ~/Engine/Engine.manifest and ~Editor/Editor.manifest files
- Paste them into the same directory in UE5.6 instead, so C:/Program Files/Epic Games/UE_5.6/Engine/Content/Localization/
I was able to run the Gather Text commandlet using the Localization Dashboard after doing so
