I am encountering an issue with the Localization Dashboard in UE5 where I receive frequent file write errors, and as a result, translations are not correctly applying in-game.
Workflow:
Set Native Culture to Japanese (ja) and gathered text.
Exported as a .po file, converted to CSV, and added English (en) translations.
Imported the updated data back into the Localization Dashboard.
While approving translations in the “Needs Review” section, I get the following error repeatedly:
TranslationEditor: Error: Failed to write localization entries to file ‘[ProjectPath]/Content/Localization/Easy Game UI/ja/Easy Game UI.archive’
The Problem:
Write Error: This error triggers every 3–5 clicks when approving items in “Needs Review.” It seems to happen whenever multiple write operations occur in succession.
In-game: When launching in Standalone mode and switching to English, most text remains in Japanese; only a few entries are updated.
Troubleshooting: The file is definitely not set to “Read-only.” I suspect a conflict with background software or an environment issue.
Questions:
Does anyone know why this .archive write error occurs, or how to resolve it?
What is the recommended workflow for using external tools (like Google Sheets/CSV) for localization to avoid these issues?
Could this be a local environment issue, or is it a known bug in UE5? Any advice would be greatly appreciated.
