ethers v6.x broke getContractAt() and probably other functions too

After the recent update to ethers to v6.x some functions like getContractAt() throws an error ->

Error HH604: Error running JSON-RPC server: ERROR processing /deploy/00_deployMock.js:
TypeError: Cannot read properties of undefined (reading 'JsonRpcProvider')

My current code looks like this ->

module.exports = async ({ deployments, getNamedAccounts, ethers }) => {
  const { deploy } = deployments;
  const { deployer } = await getNamedAccounts();

  const Mock = await deploy("MockUSDC", {
    from: deployer,
    log: true,
  });

  const signer = await ethers.getNamedSigner("mul_wallet");
  const mock = await ethers.getContract("MockUSDC", Mock.address, signer);

  console.log(mock.address);
};

module.exports.tags = ["MockUSDC"];

The hardhat.config file is like

require("@nomicfoundation/hardhat-toolbox");
require("@nomiclabs/hardhat-ethers");
require("hardhat-deploy");

/** @type import('hardhat/config').HardhatUserConfig */
module.exports = {
  solidity: "0.8.17",
  networks: {
    hardhat: {
      chainId: 31337,
    },
  },
  namedAccounts: {
    deployer: {
      default: 0,
    },
    mul_wallet: {
      default: 1,
    },
  },
};

Now, when I degraded the version back to something like ethers@5.4.7 the above function doesn't generate any error and works as intended.

Might be an ethers issue in the first place. Thank you.
