Thanks James, I had totally forgotten that I had raised the topic here. I have since found the solution and its working perfectly well. Here’s the code I am using for reference:

<div class="post">
						
						<?php 

						$relatedd = get_field('related');

						?>
						<?php if( $relatedd ): ?>
							
							<?php foreach( $relatedd as $related ): ?>
								
									<div class="post-image related">
									
									<?php if (has_post_thumbnail($related->ID) ) : ?>
									<?php echo get_the_post_thumbnail($related->ID, 'tab-small'); ?>
									<?php endif; ?>

									</div><!-- .post-image -->
									
									<div class="post-content">
									<h3><a href="<?php echo get_permalink( $related->ID ); ?>">
										<?php echo get_the_title( $related->ID ); ?>
										 <?php /* echo wp_trim_words( get_the_title( $related->ID ), 01, '...' ); // trim the words in a title to first word */ ?> 
									</a></h3>
									<?php echo custom_field_excerpt( $related->ID ); ?>
									</div><!-- .post-content -->
								
							<?php endforeach; ?>
							
						</div><!-- .post -->

The above code works in the CPT page template and in addition here is the code for the functions.php:

function custom_field_excerpt($related_post_id) {
	global $post;
	$text = get_field('introduction', $related_post_id );
	if ( '' != $text ) {
		$text = strip_shortcodes( $text );
		$text = apply_filters('the_content', $text);
		$text = str_replace(']]>', ']]>', $text);
		$excerpt_length = 70; // 20 words
		$excerpt_more = apply_filters('excerpt_more', ' ' . '[...]');
		$text = wp_trim_words( $text, $excerpt_length, $excerpt_more );
	}
	return apply_filters('the_excerpt', $text);
}

The above code shortens the text from the Introduction field and uses it in related posts.

Hope it is useful for anybody looking for similar solution.
