How to stop vscode to edit a file on save?

I have a very silly issue , i have this line of code :

 const [fontsLoaded] = useFonts({    Manrope: require("./assets/fonts/Manrope-Regular.ttf"),  });

so as the gif shows ( very low quality sorry ) on saving the file it changes the font name from "Manrope" to Manrope which makes it nonassignable as a property , but the value needs to be a string , any idea why ?
