The example below doesn’t work since beta.12. It gives “The router is already started” exception. (It works fine before Beta.12). How to solve the issue? Any help would be appreciated.

```auto
import { IAurelia } from 'aurelia';
 
export class AboutPage {
  static inject = [IAurelia];

  items = [1, 2, 3];

  constructor(aurelia) {
    this.au = aurelia;
  }

  attached() {
    const itemList = document.getElementById('my-container');
    itemList.innerHTML = "<div repeat.for='item of items'>${item}</div>";
    this.au.enhance({component: { items: this.items }, host: itemList});
  }
}
```

it’s an issue with unintentional discovery of app tasks when calling enhance. A similar issue reported here [feat(enhance): call app tasks with `.enhance` API by bigopon · Pull Request #1916 · aurelia/aurelia · GitHub](https://github.com/aurelia/aurelia/pull/1916#issuecomment-1985034744)

You can apply the work around for now, and it’ll be fixed in beta 14.
