I worked through detailed debugging to understand how to write a generator that works with the latest yeoman yo and generator. At this point none of the Yeoman documentation describes how to build a working generator with the latest version. Here's a fully functioning example that uses the latest version of yeoman and the yeoman generator: https://github.com/yenoh2/generator-hac-tf-module

update your package.json adding "type": "module"
Since the newer version uses ESM you need to update your generator use imports instead of 'require' in your index.js file.
Example:
import _ from 'lodash';
import Generator from 'yeoman-generator';
import askName from 'inquirer-npm-name';
import { createRequire } from 'module';
const require = createRequire(import.meta.url);
// see full example here: https://github.com/yenoh2/generator-hac-tf-module/blob/master/generators/app/index.js
Your export for your extended generator should look like this:
export default class extends Generator {
