Definition for rule 'react/jsx-filename-extension' was not found

Question

on a React project I am having this error Definition for rule 'react/jsx-filename-extension' was not found on some imports, for example on:

import "./App.css";
import { useState } from "react";
import { SxProps } from "@mui/material";

etc

I've read this post which gives some suggestions. However I do not want to disable that rule. And I do not have a webpack.config.js file.

Here is the eslint.js:

module.exports = {
  root: true,
  parser: "@typescript-eslint/parser",
  parserOptions: {
    project: "./tsconfig.json",
    ecmaVersion: 2018, // Allows for the parsing of modern ECMAScript features
    sourceType: "module", // Allows for the use of imports
    ecmaFeatures: {
      jsx: true, // Allows for the parsing of JSX
    },
  },
  plugins: ["@typescript-eslint", "react-hooks", "import"],
  extends: ["airbnb-typescript", "plugin:react-hooks/recommended", "prettier"],
  rules: {
    "import/no-extraneous-dependencies": 0,
    "import/prefer-default-export": 0,
    "react/react-in-jsx-scope": 0,
    "react/require-default-props": 0,
    "react/jsx-props-no-spreading": 0,
    "jsx-a11y/anchor-is-valid": 0,
    "react/no-unused-prop-types": 0,
    "@typescript-eslint/no-unused-vars": 0,
    "react-hooks/exhaustive-deps": 1,
    "no-param-reassign": [
      "error",
      { props: true, ignorePropertyModificationsFor: ["state"] },
    ],
  },
};

Here is the tsconfig.js:

{
  "compilerOptions": {
    "target": "es6",
    "lib": ["dom", "dom.iterable", "esnext"],
    "allowJs": true,
    "skipLibCheck": true,
    "esModuleInterop": true,
    "allowSyntheticDefaultImports": true,
    "strict": true,
    "forceConsistentCasingInFileNames": true,
    "noFallthroughCasesInSwitch": true,
    "module": "CommonJS",
    "moduleResolution": "node",
    "resolveJsonModule": true,
    "isolatedModules": true,
    "noEmit": true,
    "jsx": "react-jsx"
  },
  "include": ["src"],
}

And the package.json

{
  "name": "appname",
  "version": "0.1.0",
  "private": true,

    ]
  },

    "eslint-plugin-react-hooks": "^4.6.0",
    "prettier": "^2.8.4"
  }
}

Can anyone help me out to fix this error?
