Unexpected '!' in 'worker-loader!mapbox-gl/dist/mapbox-gl-csp-worker'

hi I'm trying to use mapbox-gl in React with this tutorial. and I'm getting this error : Unexpected '!' in 'worker-loader!mapbox-gl/dist/mapbox-gl-csp-worker' while importing "worker-loader!mapbox-gl/dist/mapbox-gl-csp-worker"

here is my important codes:

Map.js

import React from 'react'
import mapboxgl from 'mapbox-gl/dist/mapbox-gl-csp';
import MapboxWorker from 'worker-loader!mapbox-gl/dist/mapbox-gl-csp-worker';

mapboxgl.workerClass = MapboxWorker;
mapboxgl.accessToken = " the token ";

export default class Map extends React.Component {
    constructor(props) {
        super(props);
        this.state = {
            lng: -70.9,
            lat: 42.35,
            zoom: 9
        };
        this.mapContainer = React.createRef();
    }
    componentDidMount() {
        const { lng, lat, zoom } = this.state;
        const map = new mapboxgl.Map({
            container: this.mapContainer.current,
            style: 'mapbox://styles/mapbox/streets-v11',
            center: [lng, lat],
            zoom: zoom
        });
    }

    render() {
        const style = {
            "position": "absolute",
            "top": "0",
            "right": "0",
            "left": "0",
            "bottom": "0"
        }
        const { lng, lat, zoom } = this.state;
        return (
            <div>
                <div ref={this.mapContainer} className={style} />
            </div>
        );
    }
}

index.js

import React from 'react';
import ReactDOM from 'react-dom';
import reportWebVitals from './reportWebVitals';
import Map from "./Map";

ReactDOM.render(
    <Map/>,
  document.getElementById('root')
);

reportWebVitals();
