How can I get Slick Slider to display the images? I have a &quot;test&quot; content type with a title, body, and a media entity field that allows for multiple images. I installed Slick Slider 2.2. I mostly followed the steps outlined here: https://www.ostraining.com/blog/drupal/how-to-use-the-slick-module-in-drupal-8/.
I configured the field to use the Slick Media formatter.

When I add a node with the &quot;test&quot; content type and add two images in the image field, the next/prev buttons appear but I can't see the images. See video of slider animation.
I tried this on two different content types and I also tried using layout builder and got the same result.
I don't see any console errors.
I am running:

Drupal: 8.9.3
Slick: 2.2
I accomplished what you're trying to do using Slick Carousel together with Slick Views.
You can create a content-type that you intend to be aggregated into the slideshow.  In my case a testimonial type consisting of a background image and overlying text.
You can create a views block and set its format to Slick Carousel.  You will be provided with setting options to configure the slideshow as you wish.
Filter your view by the content-type you want to comprise your slideshow, in my case testimonial.
lastly, pull your views block slideshow into another piece of content via entity reference.
