"Language Strings" are the text data of the game. The Sims 4 does not have words "hard-coded" into the game engine. Instead, the game uses a system of placeholders (keys) and definitions (strings).
If removing your mods does not fix the issue, corrupted cache files might be forcing the game to read broken data structures. Clearing your cache is perfectly safe and will force the game to generate fresh, clean data upon launch. Navigate to Documents > Electronic Arts > The Sims 4 . Delete the file named .
This fix only works for the language your game is currently set to. If you want to change languages entirely, you may need to adjust settings in your launcher first.
Language strings, also known as localization or L10n, refer to the text and formatting used in the game to display information to players. This includes text such as menu options, button labels, and in-game notifications. In essence, language strings are the words and phrases that make up the game's user interface.
