Why webpack-dev-server stopped following/updating changed css after update?

Question

webpack

Everything worked well, but after I updated to the fifth webpack , and updated resp. webpack-dev-server, webpack-dev-server stopped following/updating changed css. That is, when the application is running and I change the html in any file, it immediately sees and updates the changes, but if I change the css file, it does not update anything else.

Here is the script from package.json.
I used to have: "start": "webpack-dev-server --mode development --hot" but I read that webpack serve should now be used . I start , as before, with the npm start command.

"scripts": {
        "test": "echo \"Error: no test specified\" && exit 1",
        "start": "webpack serve --mode development --hot",
        "build": "webpack --mode production"
    },

These are the plugin versions:

"sass": "^1.26.11",
"sass-loader": "^10.0.4",
"style-loader": "^2.0.0",
"webpack": "^5.3.0",
"webpack-cli": "^4.1.0",
"webpack-dev-server": "^3.11.0"

And this is the webpack.congig.js config.
All I added was devServer , since without it it gave an error after the update.

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

module.exports = {
    mode: "development",
    entry: "./src/index.js",
    output: {
        path: path.join(__dirname, "/dist"),
        filename: "[name].js",
        sourceMapFilename: "[name].js.map",
    },
    devServer: {
        contentBase: "/dist",
        watchContentBase: true,
        open: true,
        inline: true,
        hot: true,
    },
    module: {
        rules: [
            {
                test: /\.js$/,
                exclude: /node_modules/,
                use: ["babel-loader"],
            },
            {
                test: /\.css$/,
                use: ["style-loader", "css-loader"],
            },
            {
                test: /\.s[ac]ss$/i,
                use: ["style-loader", "sass-loader"],
            },
            {
                test: /\.(jpe?g|png|gif|woff|woff2|eot|ttf|svg)(\?[a-z0-9=.]+)?$/,
                use: [
                    {
                        loader: "url-loader",
                        options: {
                            limit: 100000,
                        },
                    },
                ],
            },
        ],
    },

    plugins: [
        new HtmlWebpackPlugin({
            template: "./src/index.html",
        }),
    ],
}

Has anyone encountered such a problem?
Thanks
