TypeError: ethers.Wallet.fromEncryptedJsonSync is not a constructor

I'm trying to run this piece of code to deploy a smart contract in JS with ethers.js library:

<!-- begin snippet: js hide: false console: true babel: false -->

<!-- language: lang-js -->

const ethers = require("ethers");
const fs = require("fs-extra");
require("dotenv").config();

async function main() {
  const provider = new ethers.ethers.JsonRpcProvider(process.env.RPC_URL);
  // reads the json private key from file
  const encryptedJson = fs.readFileSync("./.encryptedKey.json", "utf-8");

// ========= START FAILING PART ============
let wallet = new ethers.Wallet.fromEncryptedJsonSync(
encryptedJson,
process.env.PRIVATE_KEY_PASSWORD
);
// ========= END FAILING PART ============

  wallet = await wallet.connect(provider);
  const abi = fs.readFileSync("./SimpleStorage_sol_SimpleStorage.abi", "utf-8");
  const binary = fs.readFileSync(
    "./SimpleStorage_sol_SimpleStorage.bin",
    "utf-8"
  );
  
  const contractFactory = new ethers.ContractFactory(abi, binary, wallet);
  console.log("Deploying, please wait...");
  const contract = await contractFactory.deploy({ gasPrice: 1000000000000 });
}

main()
  .then(() => process.exit(0))
  .catch((error) => {
    console.error(error);
    process.exit(1);
  });

<!-- end snippet -->

but I keep getting this error in the console:

TypeError: ethers.Wallet.fromEncryptedJsonSync is not a constructor

Can someone explain why this is failing? I think I'm calling the function fromEncryptedJsonSync() correctly (as explained in the EthersJS v5 docs, see the following link: ethers.Wallet.fromEncryptedJsonSync); I couldn't find the ethers.js v6 docs since they are still building it.

Remove new as it creates a constructor

let wallet = ethers.Wallet.fromEncryptedJsonSync(
  encryptedJson,
  process.env.PRIVATE_KEY_PASSWORD
);
