Why did my webpack suddenly stop working?-CodePudding

I have been working on a project for a few days and my webpack suddenly stopped working today. I have 182 errors and 3 warnings everytime I compile everything. Here are all the errors I get:

This is no longer the case. Verify if you need this module and configure a polyfill for it.

Did you mean './util'?
Requests that should resolve in the current directory need to start with './'.
Requests that start with a name are treated as module requests and resolve within module directories (node_modules).
If changing the source code is not an option there is also a resolve options called 'preferRelative' which tries to resolve these kind of requests in the current directory too.

The errors are repeated over and over again in the console. On the client side, we see this error: Uncaught error: Cannot find module 'fs'. But this error is in some file called lifecycle.js that I did not create.

I have tried reinstalling all the node modules and webpack. It didn't work. Here is my package.json:

{
  "name": "monarchatfinal",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1",
    "build": "webpack"
  },
  "keywords": [],
  "author": "",
  "license": "ISC",
  "devDependencies": {
    "webpack": "^5.75.0",
    "webpack-cli": "^5.0.1"
  },
  "dependencies": {
    "firebase": "^9.15.0"
  }
}

and here is my webpack.config.js:

const path = require('path')

module.exports = {
    mode: 'development',
    entry: ['./src/index.js', './src/chat.js', './src/login.js', './src/signup.js'],
    output: {
        path: path.resolve(__dirname, 'dist/js'),
        filename: '[name]bundle.js'
    },
    watch: true
}

Thanks for whoever tries to help.

I have solved the problem. This is a message to everyone looking on the internet for a solution to their problem: Somehow and someway a little line of code (a useless one as a matter of fact) slipped into my code. This little line caused all the errors. So, look in all your files and you might just find the little problem.
