I edited the file \resources\i18n\ja-JP\source.ts because some translations were wrong, such as the exclusive words for StarRail, but they are not applied after restart.

You only need to translate in Crowdin and wait for the next version update to apply translation. The application will not automatically download new versions of translation.
I edited the file
\resources\i18n\ja-JP\source.ts
because some translations were wrong, such as the exclusive words for StarRail, but they are not applied after restart.
