Running into “Cannot read properties of undefined (reading ‘prototype’)” in the Process of upgrading from react-scripts 4 > 5

I currently try to upgrade my react-scripts from 4 > 5 (5.0.1). I was facing issues related to react-scripts (as many other did) not providing polyfills and therefore was following this Guide to provide those.

My config-overides.js (as described in the Guide) looks like this:

const webpack = require('webpack');
module.exports = function override(config) {
    const fallback = config.resolve.fallback || {};
    Object.assign(fallback, {
        "crypto": require.resolve("crypto-browserify"),
        "stream": require.resolve("stream-browserify"),
        "assert": require.resolve("assert"),
        "http": require.resolve("stream-http"),
        "https": require.resolve("https-browserify"),
        "os": require.resolve("os-browserify"),
        "url": require.resolve("url"),
        "buffer": require.resolve("buffer"),
        "path": require.resolve("path"),
        "process/browser": require.resolve("process/browser"),
        "querystring": require.resolve("querystring-es3"),
        "zlib": require.resolve('browserify-zlib'),
        "vm": require.resolve("vm-browserify"),
        "async_hooks": require.resolve("async-hooks"),
        "fs": false,
        "net": false,
        "express": require.resolve("express")
    })
    config.resolve.fallback = fallback;
    config.plugins = (config.plugins || []).concat([
        new webpack.ProvidePlugin({
            process: 'process/browser',
            Buffer: ['buffer', 'Buffer']
        })
    ])
    return config; }

and im using react 18.2.0 and express 4.19.2.

Now when I want to run the application (npm start) I am facing this error:

Cannot read properties of undefined (reading 'prototype')

As the error suggest, there seems to be something wrong with express (at ./node_modules/express/lib/response.js).

I already tried to change the variable declaration from var to let in the response.js as described here aswell changing "express": require.resolve("express") to "express": false. However this did not change anything.

I appreciate any suggestions or help. Thanks in advance.
