Answer 1

we just hit the same issue when trying to use Yarn instead odf npm for our projet. A solution for us was to add some dependencies to the devDependencies part in package.json.

For your issue I'd try to add @angular-devkit/build-angular and/or webpack-dev-server and/or webpack-dev-middleware and/or webpack, with the good versions, regarding they're already in your package.json or not

In my case it was

"webpack-dev-server": "4.15.0",
"webpack-dev-middleware": "6.1.0"
