How to display related posts using the Advanced Custom Fields plugin?

Question

Taxonomy

Good afternoon!
There was such a problem.
Using the Toolset plugin, I created 2 sections. This is the program and speakers.
Made the output of the program on the page

<?php 
                // Заданые переменые
                $args = array(
                    'den_programma' => 'pervyj-den',
                    'order' => 'ASC'
                );
                $query = new WP_Query( $args );
                ?> 
                <?php if ( $query->have_posts() ) {
                        while ( $query->have_posts() ) {
                        $query->the_post(); ?>  
<?php }} else {
                        echo 'Постов не найдено';
                    } ?>
                <?php wp_reset_postdata() ?>

Inside this loop, I need to output the speakers. (Speakers added separately). Thought to do it with Advanced Custom Fields plugin and Relationship fields. but that's the problem is not displayed.
I derive a standard function from the documentation

<?php
$posts_field = get_field('field_spikers2');

if( $posts_field ): ?>
    <ul>
    <?php foreach( $posts_field as $post): // variable must be called $post (IMPORTANT) ?>
        <?php setup_postdata($post); ?>
        <li>
            <a href="<?php the_permalink(); ?>"><?php the_title(); ?></a>
            <?php the_field('your_custom_field',$post); ?>
        </li>
    <?php endforeach; ?>
    </ul>
    <?php wp_reset_postdata(); // IMPORTANT - reset the $post object so the rest of the page works correctly ?>
<?php endif; ?>

Does not work. Maybe someone did something similar.
Thanks in advance!!!

And won't work. Display cycles incorrectly. As I understand it, you have 2 custom entries Programs and Speakers and you want to output data from one to the other, then the technology will be as follows:
1. Make a file to display the Program page, depending on the name of the custom entry, the file should have the same name single-{record slug (programm for example)}.php
2. copy this file to the root of the theme
3. And now, in the file itself, display the necessary Relationships using the regular code from ACF
