Hardhat Config Error HH100: Network goerli doesn't exist

I am trying to deploy a contract on Goerli, but I constantly get the error Error HH100: Network goerli doesn't exist

Here is my hardhat.config.ts

require("dotenv").config();import { task } from 'hardhat/config';import '@nomiclabs/hardhat-waffle';import '@typechain/hardhat'import '@nomiclabs/hardhat-ethers';import { HardhatUserConfig } from "hardhat/config";const PrivateKey = "b427...";const config: HardhatUserConfig = {  solidity: {        version: '0.8.0',        },  networks: {        goerli: {                chainId: 5,                url: "https://goerli.infura.io/v3/309820d3955640ec9cda472d998479ef",                accounts: [PrivateKey],        },  }, };// This is a sample Hardhat task. To learn how to create your own go to// https://hardhat.org/guides/create-task.htmltask('accounts', 'Prints the list of accounts', async (taskArgs, hre) => {  const accounts = await hre.ethers.getSigners();  for (const account of accounts) {    console.log(account.address);  }});// You need to export an object to set up your config// Go to https://hardhat.org/config/ to learn moreexport default {  solidity: '0.8.0',};

Thanks!

I don't know what I should add more, but please just ask and I will post more information.
