Every time I start up my app I get the following errors:

Compiled with problems:X

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

If you want to include a polyfill, you need to:
    - add a fallback 'resolve.fallback: { "stream": require.resolve("stream-browserify") }'
    - install 'stream-browserify'
If you don't want to include a polyfill, you can use an empty module like this:

Module not found: Error: Can't resolve 'os' in 'C:\Users\willk\WillKristiansen Dropbox\Will Kristiansen\PC\Documents\Development\react-web3\node_modules\xhr2-cookies\dist'

BREAKING CHANGE: webpack < 5 used to include polyfills for node.js core modules by default.
This is no longer the case. Verify if you need this module and configure a polyfill for it.

If you want to include a polyfill, you need to:
    - add a fallback 'resolve.fallback: { "os": require.resolve("os-browserify/browser") }'
    - install 'os-browserify'
If you don't want to include a polyfill, you can use an empty module like this:
    resolve.fallback: { "os": false }

So I did what it asked me to do and I created a fallback for every error that I got.

module.exports = {

    resolve: {
        fallback: { stream: require.resolve('stream-browserify') }
    },

    resolve: {
        fallback: { crypto: require.resolve('crypto-browserify') }
    },

    resolve: {
        fallback: { assert: require.resolve('assert/') }
    },

    resolve: {
        fallback: { http: require.resolve('stream-http') }
    },

    resolve: {
        fallback: { https: require.resolve('https-browserify') }
    },

    resolve: {
        fallback: { url: require.resolve('url/') }
    },

    resolve: {
        fallback: { os: require.resolve('os-browserify/browser') }
    },
}

assert and url are the only ones that worked in fixing the error, but all the other fallbacks were ignored entirely. I have tried variations of the syntax such as:

resolve: {
        fallback: { "stream": require.resolve('stream-browserify') }
    },

but that didn't work either. I've updated npm, web3, uninstalled and reinstalled stream-browserify locally and globally, updated node, etc. I am a very new programmer so I don't know what else to try. Has anyone had this issue before?
