Facing yParity error while simply deploying a contract.

[Zartaj0]

EDIT: Just noticed that there's no problem in deploying the contract, means the contract is being deployed but after deployment some getTransaction function is failing. As per #3835 this was fixed in 6.6.4. Now the problem is no matter what version I am installing, whenever I log the ethers.version, it shows 6.6.1. what can be the problem??

I am trying to deploy some contracts and tried using different versions of ethers.

The deployment works for Mumbai testnet but not for sepolia,

Deployment Script :

const { ethers } = require("hardhat")

async function main() {
    console.log("deploying logic");
  
    const logic = await ethers.deployContract("GovernorBravoDelegate");
    await logic.waitForDeployment();
  
    console.log("logic deployed on", logic.target);
  }
  
  main();

"dependencies":

    "@nomiclabs/hardhat-ethers": "^2.2.3",
    "@nomiclabs/hardhat-etherscan": "^3.1.8",
    "@openzeppelin/contracts": "^3.3.0",
    "dotenv": "^16.4.1",
    "ethers": "^5.0.0",
    "hardhat": "^2.19.5"
  }

Error :

After trying different solutions, I managed to match the different version problems, and this line require("@nomicfoundation/hardhat-ethers"); was missing in my config, due to which there was a confusion between different version.

Also the npm package of hardhat-ethers shows the latest version as 2.2.3 but the original one is this, and this was major point because of which I got stuck.
