TypeError in Hardhat-Chai Matchers - isAddress not a function

I'm encountering a TypeError in my Hardhat test script that involves the isAddress function from the @nomicfoundation/hardhat-chai-matchers library. The error seems to be causing issues with my test suite. Below is the relevant code snippet: here my code.

const { expect, assert } = require("chai");

const { ethers } = require("hardhat");

const {

  addressFactory,

  addressRouter,

  addressFrom,

  addressTo,

} = require("../utils/AddressList");

const { erc20ABI, factoryABI, routerABI } = require("../utils/AbiList");

describe("read and write blockchain", () => {

  let provider,

    contractFactory,

    contractRouter,

    contractToken,

    decimals,

    amountIn,

    amountOut;

  before(async () => {

    provider = new ethers.providers.JsonRpcProvider(

      ""

    );

    contractFactory = new ethers.Contract(addressFactory, factoryABI, provider);

    contractRouter = new ethers.Contract(addressRouter, routerABI, provider);

    contractToken = new ethers.Contract(addressFrom, erc20ABI, provider);

  });

  it("connects to the provider, factory, token, and router", () => {

    assert(provider._isProvider);

    expect(contractFactory.address).to.equal(

      "0x5C69bEe701ef814a2B6a3EDD4B1652CB9cc5aA6f"

    );

    expect(contractRouter.address).to.equal(

      "0x7a250d5630B4cF539739dF2C5dAcb4c659F2488D"

    );

    expect(contractToken.address).to.equal(

      "0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2"

    );

  });

});

I'm trying to perform [read and write blockchain] in my Hardhat tests, and the tests are failing due to the following error: I tried downgrade the ethers version to 5.6.1 and didn't fix.

Here what I get.

read and write blockchain
    1) connects to the provider, factory, token, and router


  0 passing (73ms)
  1 failing

  1) read and write blockchain
       connects to the provider, factory, token, and router:

This happens when versions of ethers collide - I think you might be using version 5.X in your code yet the version of hardhat-chai-matchers you're using depends on 6.X.

If that's the case, look for an older version of hardhat-chai-matchers or update your version to 6
