Translation file missing error it.json in React Native Debugger

[Angelk90]

Description

Error:

Launching DevTools...
Error: ENOENT: no such file or directory, stat '/Users/NameUser/Desktop/app/node_modules/
@react-native/debugger-frontend/dist/third-party/front_end/core/i18n/locales/it.json'
 MAP  ./index.js 

When launching the debugger for a React Native app, the error ENOENT: no such file or directory occurs, indicating that the system cannot find the it.json translation file needed for Italian localization.

This file should be located in the @react-native/debugger-frontend package folder, but it is missing.

The error prevents the debugger from working properly, which attempts to load the Italian UI, but fails to do so due to the missing translation file.

Steps to reproduce

1. yarn start
2. yarn android
3. Place yourself on the shell where you executed the yarn start command
4. Press j

React Native Version
