Why doesn't babel want to compile es-6 code??

Question

JavaScript

Hello. I am learning to set up a react project myself using webpack.
Installed all required packages. Registered a config file for webpack, babel.

webpack

const path = require("path");
const HtmlWebpackPlugin = require("html-webpack-plugin");

module.exports = {
    devtool: "cheap-module-source-map",
    entry: [
        "./src/js/index"
    ],
    output: {
        path: path.join(__dirname, "dist/js"),
        filename: "bundle.js"
    },
    module: {
        rules: [
            {
                test: /\.(js|jsx)$/,
                exclude: "/node_modules",
                use: {
                    loader: "babel-loader"
                }
            }
        ]
    },
    plugins: [
        new HtmlWebpackPlugin({
            template: './src/index.html'
        })
    ]
};

package.json

{
  "name": "movie-app",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "start": "webpack-dev-server --open --mode development --hot",
    "build": "webpack --mode production",
    "test": "echo \"Error: no test specified\" && exit 1"

  },

    "react-dom": "^16.4.2"
  }
}

.babelrc

{
  "presets": ["env", "react"]
}

I created a react component, I run the build and a trace falls out to my console. error

I don't understand why babel can't recompile ES6?
PS I know that you can set a separate preset for the arrow functions, but I'm wondering why it doesn't work now.
I use babel-preset-envbecause babel-preset-es2015deprecated

class properties is an experimental syntax.
babel-preset-stage-0 install. .babelrc:

{
  "presets": ["env", "react", "stage-0"]
}
