 Hello @ironprogrammer!

 Tried to setup a site to help you to reproduce the problem:
 1. https://www.gigitopcinformatica.it/test4/hello-world/
 theme active: wordpress twenty-twentytwo, inserted in function.php the
 code:
 {{{
 add_filter( $hook_name='wp_content_img_tag', function( $filtered_image,
 $context, $attachment_id ){

 $timestamp_mediapost = get_post_modified_time( $format='U', $gmt=true,
 $post=$attachment_id, $translate=false );
 $filtered_image = str_replace( $search='.webp',
 $replace='.webp?='.$timestamp_mediapost, $subject=$filtered_image,
 $count);
 echo $count.'-';

 return $filtered_image; },$priority=21, $accepted_args=3 );
 }}}

 Objective: add query strings to webp files. Please use console to look at
 filtered images code ad look to the top the echoed $count parameter. Seem
 that the order is: custom logo image, then content image, then custom logo
 image again, the, content image again.
