TypeError: Class extends value undefined is not a constructor or null

Hi Team, I'm a bit amateur to TS, but I do write solidity and work my way around with hardhat, lately, I've been encountering an error that has given me a lot of pain. The error stack goes like this:

TypeError: Class extends value undefined is not a constructor or null
    at Object.<anonymous> (/**********/node_modules/hardhat-gas-reporter/src/lib/provider.ts:11:42)
    at Module._compile (node:internal/modules/cjs/loader:1256:14)
    at Module._extensions..js (node:internal/modules/cjs/loader:1310:10)
    at Object.require.extensions.<computed> [as .js] (*********/node_modules/ts-node/src/index.ts:1608:43)
    at Module.load (node:internal/modules/cjs/loader:1119:32)
    at Function.Module._load (node:internal/modules/cjs/loader:960:12)
    at Module.require (node:internal/modules/cjs/loader:1143:19)

    at Object.<anonymous> (**********/node_modules/hardhat-gas-reporter/src/index.ts:16:1)
    at Module._compile (node:internal/modules/cjs/loader:1256:14)

So I went on to the provider.ts file which has:

So I changed the path to: import { ProviderWrapper } from "hardhat/internal/core/providers/wrapper";

But still on running npx hardhat compile I'm getting the same error, I've cleaned the cache as well, but same output again. Would someone be able to help me out here?

@schrute08 Could you show your package.json, typescript config and hardhat config so I can see how your project is setup and all the versions you're using?

Yes @cgewecke , here: https://gist.github.com/schrute08/c830e1e2b29dafc8209a0743d41cc97d

@schrute08 Could you see if this problem resolves by updating hardhat to a more recent version? (Like 2.22.10?)

The minimum version supported by this plugin is 2.16.0 and your package has 2.12.4
