Error with @reduxjs/toolkit and Typescript - TS1005

After installing the required packages to run react-redux and @reduxjs//toolkit in my current projects, I ran into this error after running npm start:

TypeScript error in C:/Users/xxx/Documents/xxx/node_modules/@reduxjs/toolkit/dist/configureStore.d.ts(1,13):
'=' expected.  TS1005
 1 | import type { Reducer, ReducersMapObject, Middleware, Action, AnyAction, StoreEnhancer, Store, Dispatch, PreloadedState, CombinedState } from 'redux';

My store is this:

import { configureStore } from "@reduxjs/toolkit";
import securityReducer from "../features/security/securitySlice.js";
const store = configureStore({
    reducer: {
      security: securityReducer,
  },
  });
export default store;

My index.tsx file contains this:

import React, { useEffect, useState } from "react";
import ReactDOM from "react-dom";`
import "./index.css";`
import AppContainer from "./AppContainer.js";
import * as serviceWorker from "./serviceWorker";
import store from "./app/store.jsx";
import { Provider } from "react-redux";
ReactDOM.render(
  <React.StrictMode>
    <Provider store={store}>
      <AppContainer />
    </Provider>
  </React.StrictMode>,
  document.getElementById("root")
);
serviceWorker.unregister();

And my package.json file is this:

I read from some posts that my version of typescript needed to be updated to 3.8 but it still doesn't seem to solve the issue.

Thank you so much if anyone knows how to fix this error.
