The code above was missing the $match rules so although you could see the correct pages in the location rules, the ACF rule wouldn’t get applied to anything. This should work:

/*
* ACF post parent
*/

add_filter('acf/location/rule_types', 'acf_location_rules_types');
function acf_location_rules_types( $choices )
{
    $choices['Custom Post types']['cpt_parent'] = 'Custom post type parent';
 
    return $choices;
}
add_filter('acf/location/rule_values/cpt_parent', 'acf_location_rules_values_cpt_parent');
function acf_location_rules_values_cpt_parent( $choices )
{
	$args = array(
		'hierarchical' => true,
		'_builtin' => false
	);
    $posttypes = get_post_types( $args );
 
    if( $posttypes )
    {
        foreach( $posttypes as $posttype ):
        
			if( $posttype != 'acf' ):
				$args = array(
				'post_type' => $posttype,
				'posts_per_page' => -1,
				'post_status' => 'publish'
				);
				$customposts = get_posts( $args );  
				if ( $customposts  ) {
					foreach( $customposts as $custompost ){
						$choices[ $custompost->ID] = $custompost->post_title;
					}
				}
			endif;
		endforeach;
	}
 
    return $choices;
}

//MATCH THE RULE
add_filter('acf/location/rule_match/cpt_parent', 'acf_location_rules_match_cpt_parent', 10, 3);
function acf_location_rules_match_cpt_parent( $match, $rule, $options )
{
	
	global $post;
	$selected_post = (int) $rule['value'];

	// post parent
	$post_parent = $post->post_parent;
	if( $options['page_parent'] ) {
	
    	$post_parent = $options['page_parent'];
    	
	}

	if ($rule['operator'] == "=="){
		$match = ( $post_parent == $selected_post );
	}
	elseif ($rule['operator'] != "!="){
		$match = ( $post_parent != $selected_post );
	}
 
    return $match;
}
