Reproduction

• Install VSCode ESLint Extension
• Disable autoInit

Describe the bug

I have tried manually setting the VSCode extension options to look for the config file in the .nuxt directory and that doesn't work either:

  "eslint.workingDirectories": [
    {
      "directory": "./.nuxt",
      "changeProcessCWD": true,
    },
  ],
  "eslint.options": {
    "overrideConfigFile": ".nuxt/eslint.config.mjs"
  },
  "eslint.useFlatConfig": true

I think it must be an issue with the generated eslint.config.mjs as this is the output of the ESLint extension, see logs below.
