Webpack Source Map Export Compiled JS - reactjs

Question

I was using webpack 3, there was no hot reload issue and then I upgraded to webpack 5.
Webpack version: ^5.50.0, React version: 17.0.2
Webpack source map doesn't work properly. I attached a picture of output at the bottom.
When I read webpack documentation, there is no difference between my config with offical config.
Here is my webpack hot config for development;
const webpack = require('webpack') //to access built-in plugins
const HtmlWebpackPlugin = require('html-webpack-plugin') //installed via npm
const BundleAnalyzerPlugin = require('webpack-bundle-analyzer').BundleAnalyzerPlugin
const CopyPlugin = require('copy-webpack-plugin')
const MiniCssExtractPlugin = require('mini-css-extract-plugin')
const vendorArray = require('./vendors')
const path = require('path')
const Dotenv = require('dotenv-webpack')
module.exports = {
mode: 'development',
devtool: 'source-map',
entry: {
main: [
'react-hot-loader/patch',
'webpack-dev-server/client?http://0.0.0.0:3002',
'webpack/hot/only-dev-server',
'./src/main.js'
]
},
output: {

filename: '[name].[hash:8].js'
},
resolve: {
