Shot in the dark, as this is pretty much what you had, but give something like this a try:

//Perhaps use the field_key here
if( have_rows('content_type', $post_id) ) :
    while( have_rows('content_type', $post_id) ) : the_row();

		if(get_row_layout() == 'text_field'): //The Name of our Flexible Content Row
			
			//Perhaps use the field_key here
			if( have_rows('label') ) : 
				while( have_rows('label') ) : the_row();
					
					//Perhaps use the field_key here
					update_sub_field('subtitle', "This is a new Subtitle!");
					
				endwhile;
			endif;

		endif;

	endwhile;
endif;
