Display ACF date field in Query Loop

Hi,
I have a tricky problem that I was hoping you could give me some guidance on.

I want to display a ACF date field in a GP Query Loop. Using Dynamic Data -> Post Meta does not work unfortunately, because ACF stores dates as Ymd in the database and this is also how Dynamic Data retrieves and displays it, however I need m.d.Y

Solution I've tried but didn't work is with this shortcode:

function display_date() {
    ob_start();
    global $post;
    ?>
    <div class="event-date">
        <?php the_field('sort-datum', $post->id ) ?>
    </div>
    <?php
    return ob_get_clean();
}
add_shortcode( 'display_date','display_date' );

This just prints the date field of the first post in the loop for all posts. It seems like '$post-id' is not grabbing the right id.

My problem seems to be similar to this question. Here, the suggested solution is to use render_block() to make get_the_id() grab the correct value.

This is where I am stuck: I tried to adapt the solution proposed here , but I can't get it to work.

This is what I have:

function gt_rerender_container_add_id( $block_content, $block ) {
	if ( ! is_admin() && ! empty( $block['attrs']['className'] ) && 'add-dynamic-id' === $block['attrs']['className']  ) {
			
			$my_block = 'class="gb-headline gb-headline-d9ae39f0 gb-headline-text event-date-id';
			$id = get_the_ID( $post-> id);
            $event_date = get_field('sort-date', $id);
			$my_id = 'event-'.$event_date;
			$my_replace = 'class="gb-headline gb-headline-d9ae39f0 gb-headline-text event-date-id">Content'.$event_date;
			$new_content = str_replace($my_block, $my_replace, $block_content);
			return $new_content;
	} 
    return $block_content;
}
 
add_filter( 'render_block', 'gt_rerender_container_add_id', 10, 2 );

The block I inserted into the Query Loop Post Template is just a GP Headline block turned to a div with content 'Content'.

It's not doing anything, which means there's probably something basic I'm missing. Can you point me in the right direction?

Thank you!
