It seems that if you are using the new "improved assets loading" feature of Elementor, Swiper.js is NOT loaded by default in every Elementor page (and that's good, by the way). So you have to be sure that Swiper.js is included in your page,

For example, you can insert in your page a "sample" carousel with few images and hide it by css or responsive options. Oterwise, try to disable "improved assets loading" and check again.

The code is working when the "improved assets loading" feature is off. Nevertheless is there any way to load the swiper library with the "improved assets loading" being active? I've tried to have a carousel widget loaded but it doesn't make my custom slider work.

Well, I've made it work with "improved assets loading" enabled and an hidden image carousel widget in my page.
But, be sure to put some images in this hidden carousel (it must be a working carousle) oterwise Elementor Swiper script will not be included in your page (or at least, I guess so). Do you have any error in browser console?

Hey, @IlPizza79 thanks for the reply! Meantime I couldn't sleep cause of that and somehow after some digging, I actually made this code work with improved assets and without the need for a hidden carousel, which in my case didn't want to work even with pictures.
Here's the code I modified. Maybe it will be useful to anyone :)

`<script type="module">
import Swiper from 'https://unpkg.com/swiper@7/swiper-bundle.esm.browser.min.js'

jQuery( function( $ ) {
// add 'swiper-container' class to .elementor-container
$( '.custom-swiper > .elementor-container' ).addClass( 'swiper-container' );

// Insert 'swiper-wrapper' div into .elementor-container div
$( '.custom-swiper .swiper-container' ).append( '<div class="swiper-wrapper"></div>' );

$( '.custom-swiper .swiper-container > .elementor-column' ).appendTo( '.custom-swiper .swiper-container .swiper-wrapper' );

$( '.custom-swiper .elementor-container .swiper-wrapper > div' ).addClass( 'swiper-slide' );

// previous & next 
$( '.custom-swiper .swiper-container' ).append( '<div class="swiper-button-next"></div>' ).append( '<div class="swiper-button-prev"></div>' );

const swiper = new Swiper('.custom-swiper > .elementor-container', {

    loop: true, 
    parallax: true,
    speed: 1000, 

// Autoplay
autoplay: {
      delay: 2500,
      disableOnInteraction: false,
    },

// Navigation arrows
navigation: {
    nextEl: '.swiper-button-next',
    prevEl: '.swiper-button-prev',
  },

});

});

</script>`

@IlPizza79 Is it readable now?

Thank you for your deep insight! I have followed your blog & created a slider please checkout.
