Hardhat V3 can't compile #7578
Description
Version of Hardhat
3.0.7
What happened?
I was trying to compile my contracts after upgrading the package using bun before verifying some contracts I deployed tonight. However, now I'm getting an unexpected error:
computer@computer: ~/protocol$ bun compile
$ bunx --bun hardhat compile
An unexpected error occurred:
1 | "use strict";
2 | Object.defineProperty(exports, "__esModule", { value: true });
3 | exports.BroadcastedTxDifferentHash = exports.AccountIndexOutOfRange = exports.UnsupportedEventError = exports.NotImplementedError = exports.HardhatEthersError = void 0;
4 | const plugins_1 = require("hardhat/plugins");
5 | class HardhatEthersError extends plugins_1.NomicLabsHardhatPluginError {
^
TypeError: The superclass is not a constructor.

Minimal reproduction steps
Start up a new hardhat v3 project.
Setup the hardhat.config.ts:

import "@nomicfoundation/hardhat-toolbox";
import hardhatVerify from "@nomicfoundation/hardhat-verify";
import { HardhatUserConfig } from "hardhat/config";
import dotenv from "dotenv";
dotenv.config();
