Error: pkg.name and pkg.version required (Node.js: v17.3.0)

Yo stops working after installing generator-code:

C:\Program Files\nodejs\node_modules\yo\node_modules\update-notifier\index.js:32
                        throw new Error('pkg.name and pkg.version required');
                        ^

Note: deleting or even renaming the "generator-code" folder to something else (e.g. dummy_generator-code) solves the issue.
Re-installing generator-code or removing dummy_ makes the issue re-surface. Other generators are not affected.

Node.js: version 17.3.0
npm: 8.3.0
yo: 4.3.0
generator-code: 1.6.5

I am having the same issue.

Node: 14.18.1
npm: 8.3.0 (though happened before I tried upgrading npm too)
yo: 4.3.0 (though happened on 3.1.1 before upgrading too)
generator-code: 1.6.5

I'm not sure how to really fix this, but the issue is that there is a package.json file inside the generators/app folder, and yo is using that rather than the root package.json. And that nested package.json is missing required fields.

I was able to fix it by adding the following to the generators/app/package.json

      "name": "generator-code",
      "version": "1.6.5",
      "description": "Yeoman generator for Visual Studio Code Extensions",
