Anything else relevant?

This is not a bug with the Angular CLI but I also didn't think it was a feature request so I was unsure how to report this.

What I'd like to request is for a new version of the Angular CLI to be pushed which updates the webpack dependency to the version that is not bugged: v5.105.0.

As a workaround, after creating an Angular app with ng new I can override the webpack version in the package.json with:

  "overrides": {
    "webpack": "5.105.0"
  },

But it would be good if the non-bugged version of webpack was available by default after doing ng new.

I am having the same issue aswell using @angular-devkit/build-angular 20.3.15
It works fine when using 20.3.14 or overriding to webpack 5.103.0 or 5.105.0

This is pending in #32424 for v21.

v20 is only updated for security patches, so you'd have to keep the override there.
