Steps to reproduce:

1. Add Image content with an image of the .avif type extension.
2. Add the following SA configuration:

               content_view:
                   full:
                       article:
                           template: '@ezdesign/full/image.html.twig'
                           match:
                               Identifier\ContentType: image
   

3. Create a new .twig file with the following path: templates/themes/standard/full/image.html.twig
   and with the following content:

   {{ ez_render_field(content, 'image', {
       'template': 'fields/image.html.twig'
   }) }}
   

4. Create another .twig file with the following path: templates/fields/image.html.twig
   and with the following content:

   {% block ezimage_field %}
       {% set imageAlias = ez_image_alias( field, versionInfo, 'small' ) %}
       {% set src = imageAlias ? asset( imageAlias.uri ) : "//:0" %}
   
       <div style="background: url({{ src }});
               width: 100vh; height: 20vh"></div>
   {% endblock %}
   

5. Open the image content from step 1. on frontend.

Result:
One is presented with an exception:

An exception has been thrown during the rendering of a template ("An image could not be created from the given input") in "fields/image.html.twig".

Expected result:
The image should be rendered properly, just like it's done for other images with different than .avif extensions.
