Since the upgrade to angular18, I'm having timeout with simple component
[vite] Internal server error: Page /guide did not render in 30 seconds.

The component is used to render an image once every second, it takes into parameters the list of images
import { Component, OnInit, signal } from '@angular/core';

@Component({
  selector: 'app-root',
  standalone: true,
  template: `
    @if(img(); as img){
      <img [src]="img" />
    }
  `,
  styles: '',
})
export class AppComponent implements OnInit {
  imgs = ['https://cdn.pixabay.com/photo/2023/09/02/03/15/water-8228076_1280.jpg',
  'https://media.istockphoto.com/id/157482223/de/foto/water-splash.jpg?s=2048x2048&w=is&k=20&c=tovlRmZEzpSmlXEL9OH8iANIK2w16YQD8QDDtsmxs3U=',
  'https://media.istockphoto.com/id/157482222/de/foto/gefrorene-tropfen-wasser.jpg?s=2048x2048&w=is&k=20&c=ASd2SEWIz7EEiSQLeCdrf6zA-eR9ExAyFCzZLG1tXco='];

  img = signal('');
  intervalId:any;
  pointer=0;

  ngOnInit(): void {
    this.img.set(this.imgs[0]);
    this.startImageRotation();
  }

  startImageRotation(): void {
    this.intervalId = setInterval(() => {
      this.pointer = (this.pointer + 1) % this.imgs.length;
      this.img.set(this.imgs[this.pointer]);
    }, 1000);
  }
}

The code is working if I load another page and I navigate to this page, if I try to refresh the page directly there is a TimeOut. However it always fails if I try to run ng build. This page doesn't let me build to the project
How to reproduce the issue in few steps with ANGULAR 18 :
ng new test

Update the app.compenent.ts
import { Component, OnInit, signal } from '@angular/core';

@Component({
  selector: 'app-root',
  standalone: true,
  template: `
    @if(img(); as img){
      <img [src]="img" />
    }
  `,
  styles: '',
})
export class AppComponent implements OnInit {
  imgs = `['https://cdn.pixabay.com/photo/2023/09/02/03/15/water-8228076_1280.jpg',
  'https://media.istockphoto.com/id/157482223/de/foto/water-splash.jpg?s=2048x2048&w=is&k=20&c=tovlRmZEzpSmlXEL9OH8iANIK2w16YQD8QDDtsmxs3U=',
  'https://media.istockphoto.com/id/157482222/de/foto/gefrorene-tropfen-wasser.jpg?s=2048x2048&w=is&k=20&c=ASd2SEWIz7EEiSQLeCdrf6zA-eR9ExAyFCzZLG1tXco=']`;

  img = signal('');
  intervalId:any;
  pointer=0;

  ngOnInit(): void {
    this.img.set(this.imgs[0]);
    this.startImageRotation();
  }

  startImageRotation(): void {
    this.intervalId = setInterval(() => {
      this.pointer = (this.pointer + 1) % this.imgs.length;
      this.img.set(this.imgs[this.pointer]);
    }, 1000);
  }
}

then Serve
ng serve

You should have an error like that
