Getting ACF post_object inside wp_query

Is it possible to use the post_object field inside custom wp_query? I created a template to list all blog posts and getting different content by getting a post_format. In one of the formats, I want to get post_object from Custom Post type that I was created. What I’m struggling with is getting ACF field values from that post, even if I pass the second parameter (ID) in the_field() it gets me always fallback, for example, for a date, it always showing me today’s date.

Here is Query code:

 $args = array(  
          'post_type' => 'post',
          'post_status' => 'publish',
          'posts_per_page'=> 3,
          'paged' => $paged
      );

    $loop = new WP_Query( $args ); 
    if ( $loop->have_posts() ) :
    while ( $loop->have_posts() ) : $loop->the_post(); 
    ?>

         <?php get_template_part( 'template-parts/content', get_post_format() ); ?>

    <?php
            endwhile;
        
            wp_reset_postdata();  ?>
        <?php else : ?>
          <?php esc_html_e( 'There is no post to display' ); ?>

        <?php endif; ?>

In php file of link format I’m checking if user check that he want to load post from CPT or to enter information manually. As you can see HTML and ACF fields are the same, just if user check that field, all content is loading from CPT

<article id="post-<?php the_ID(); ?>" <?php post_class(); ?>>

      <a href="<?php echo get_permalink(); ?>">
       <h4><strong><?php the_title(); ?></strong></h4>
     </a>
    <?php 
    if ( get_field( 'dafed_promo' ) == 1 ) :
      $post_object = get_field( 'choose_dafed' );
      if ( $post_object ):
         $post = $post_object;
         setup_postdata( $post ); ?> 

      <?php if ( have_rows( 'event_details' ) ) : ?>
         <?php while ( have_rows( 'event_details' ) ) : the_row(); ?>
          <div class="event-info">
             

                   <?php  // Load field value and convert to numeric timestamp.
                    $unixtimestampdafed = strtotime( get_sub_field( 'event_time_and_date' ) );
                 ?>
                   <div class="date">
                    <div class="month"> <?php echo date_i18n( "M", $unixtimestampdafed ); ?></div>
                    <div class="number"><?php echo date_i18n( "d", $unixtimestampdafed ); ?></div>
                  </div>

            
              <strong>Vreme: </strong> <?php the_sub_field( 'event_time' ); ?><br>

I do not see you using the second argument anywhere. Assuming that event_details is a field of $post, you should pass the post ID at least to have_rows(). In case this is not it, we should find out where exactly the problem occurs:

• Have you checked if $post is being populated as intended?
• Have you checked if the ID property of $post is “ID” and not “id” or “post_id”?
• Have you factored in that when you call get_the_ID() you are asking for the ID of the current main loop item, for which you have called the template?
