Subfield in a loop not displaying

I’m displaying a loop of custom post type. The custom fields are displaying correctly, however I can’t get the subfields to display.

In this case I’ve created a custom field named project_description with a subfield called sub_heading within a group called Project Page.

This is what I’ve done so far. Can anyone tell me what I’m doing wrong?

<section class="services-section">    
                  <div class="container services-section-container">
                     <h1 class="fp-header extended-black-l">Featured Projects</h1>  
                     
                     <?php 
                      $featuredProjectSection = new WP_Query(array(
                        'posts_per_page' => 10,
                        'post_type' => 'project'
                      ));

                      while($featuredProjectSection->have_posts()) {
                      $featuredProjectSection->the_post(); $i++; if(($i % 2) == 0) { ?>
                   
                        <div class="row splitcontent-services">
                          <div class="col-lg-6 col-6 services-img-left">
                            <img src="<?php the_field('top_image') ?>">
                                         
                          </div>
                          
                          
                          <div class="col-lg-6 col-6 services-content-right">                         
                            <h2 class="condensed-semibold-l"><?php the_title(); ?></h2>
                              <?php if( have_rows('project_description') ): ?>
                              <?php while ( have_rows('project_description') ) : the_row(); 
                               $subhead = get_sub_field('sub_heading');?>                             
                            <h3 class="regular-m"><?php echo $subhead; ?></h3>
                            <?php endwhile; ?>
                            <?php endif; ?>

                            <button class="extended-black-s"><a href="<?php the_permalink(); ?>">Learn More ></a></button>
                            	
                          </div> 
                        </div>
