generated typescript typing broken: must be unknown first

When building the generated typescript, I get this error:

TS2352: Conversion of type 'Contract' to type 'AccountLoader' may be a mistake because neither type sufficiently overlaps with the other. If this was intentional, convert the expression to 'unknown' first.

Generated code:

/* Autogenerated file. Do not edit manually. */
/* tslint:disable */
/* eslint-disable */

import { Contract, Signer } from "ethers";
import { Provider } from "@ethersproject/providers";

import type { AccountLoader } from "../AccountLoader";

export class AccountLoader__factory {
  static connect(
    address: string,
    signerOrProvider: Signer | Provider
  ): AccountLoader {
    return new Contract(address, _abi, signerOrProvider) as AccountLoader;
  }
}

const _abi = <omitted for concision>

@robert-e-davidson3 most likely the code is correct but there were some incompatible changes in ethers. Can you update all ethers packages and try again? See also a similar issue in #328
