@Jatinkkalra

Add allowUnlimitedContractSize = true to your hardhat.config.js under hardhat and localhost network & then deploy.

defaultNetwork: 'hardhat',
  networks: {
    hardhat: {
      chainId: 31337, // Used when we run tests
      allowUnlimitedContractSize: true, <----- this
    },
    localhost: {
      chainId: 31337, // Used when you run `yarn hardhat node` or `yarn hardhat deploy`. A fake blockchain in the terminal.
      allowUnlimitedContractSize: true,    <---- this
    },
  },
