<img> tags not rendered in Drupal block Flexslider

I ran into this and in my case simply deleting the flexslider module folder and running "composer install" at my project root solved it. Happens to me sometimes on some servers.

I am having the same issue with Drupal 10.2.5. with FlexSlider, FlexSlider Fields, and Flexslider Views Style (all v3.0.0-alpha1). The issue is not that the images are not present on the server, but that the HTML code for the pages don’t show the HTML code that references the images. And there are no errors of any kind; Drupal and Google Chrome are behaving as if everything is working as expected. I have spent a lot of time troubleshooting with our hosting provider; since there's nothing specific coming up that suggests there's a bug or an issue.

Here's our conclusion: what's likely happening is that someone visits a different page on our live site, and that page causes something bad to be written to Drupal's internal caches, and that corrupts the slideshow somehow for subsequent page loads.

The temporary fix: Flush All Caches and the slideshow works again. Until something bad is written to Drupal's internal caches, and it corrupts the slideshow again.

The issue is not replicating for me. Attaching a short clip.

As your comment, i am assuming that JS is not refreshing

I am getting this too in a block.
the preview is fine.
when I place a block on a page and allow authenticated users access, it is fine.
but when it is anonymous, nothing shows up:
<div class="hero-slide-show view view-cci-slideshow view-id-cci_slideshow view-display-id-block_1 js-view-dom-id-92b236c0a42202ec684c918f60a908e87d2493f63cf0166c52e096023daa21b2"> </div>

So if I enable the flexslider_example module and create a block there.
If I have a paragraph and reference media from within the paragraph. I can make a block that appears.
Now if I have a content type that then has a paragraph that then has media, the media does not render in the block.
