Compilation Error, "GovernanceToken.sol"

[Mumtaz503]

My GovernanceToken.sol is throwing an error while compiling. Please help me out.

Here's my GovernanceToken.sol

// SPDX-License-Identifier: MIT

pragma solidity ^0.8.18;

import "@openzeppelin/contracts/token/ERC20/extensions/ERC20Votes.sol";

contract GovernanceToken is ERC20Votes {
    uint256 public s_maxSupply = 1000000000000000000000000;

    constructor()
        ERC20("GovernanceToken", "GT")
        ERC20Permit("GovernanceToken")
    {
        _mint(msg.sender, s_maxSupply);
    }
}

Here's the error during compilation:

DeclarationError: Identifier not found or not unique.
