I encountered this error after starting the project: Browser runtime error. The only thing I did was add webpack. Here is the reference for the webpack configuration file:

const webpack = require('webpack');
const path = require('path');
const HtmlWebpackPlugin = require('html-webpack-plugin');
const Dotenv = require('dotenv-webpack');

const config = {
  entry: './src/index.tsx',
  mode: 'development',
  devtool: 'source-map',
  output: {
    path: path.resolve(__dirname, 'dist'),
    filename: 'bundle.js'
  },
  module: {
    noParse: [/\/node_modules\/@tanstack\/react-query-devtools\//],
    rules: [
      {
        test: /\.(js|jsx)$/,
        use: 'babel-loader',
        exclude: /node_modules/
      },
      {
        test: /\.css$/,
        use: [
          'style-loader',
          'css-loader'
        ]
      },
      {
        test: /\.png$/,
        use: [
          {
            loader: 'url-loader',
            options: {
              mimetype: 'image/png'
            }
          }
        ]
      },
      {
        test: /\.svg$/,
        use: 'file-loader'
      },
      {
        test: /\.ts(x)?$/,
        loader: 'ts-loader',
        exclude: /node_modules/
      }
    ]
  },
  plugins: [
    new Dotenv(),
    new HtmlWebpackPlugin({
      template: "./src/index.html",
    }),
  ],
  resolve: {
    extensions: [
      '.tsx',
      '.ts',
      '.js'
    ]
  },
  devServer: {
    port: 3000, // 将端口3000添加到开发服务器
    hot: true, // 启用热模块替换（HMR）
    open: true, // 服务器启动时在默认浏览器中打开应用程序
    static: {
      directory: path.resolve(__dirname, 'dist'), // 设置用于提供文件的基本目录
    }
  }
};

module.exports = config;

Then I started getting materialUI errors. At first I thought I accidentally updated the package.json file, but that's not the case. I also want to point out that it worked before adding webpack. All I did was configure webpack and install some dependencies (which don't affect previous dependencies or versions!). I also encountered another error after adding webpack to the project, which I fixed using the 'patch-package' library, using the following patch file:

This is a previous bug fixed with a patch:

I tried using multiple versions of node (nodejs) to see if I could get the error multiple times. But it doesn't work either in node 14.15.0 or 18.15.0.

Another strange thing is that I can't even find the word "getUtilityClass" in the project (use ctr shit f in vsCode to find it).
