break after the first correct row type, but reset the rows or you may have issues if you need to loop over the rows again

add_filter('the_excerpt', 'your_function_name');

function your_function_name($excerpt) {
  if( have_rows('blog_post_content') ):
  
    while ( have_rows('blog_post_content') ) : the_row(); 
        if( get_row_layout() == 'blog_post_text_content' ): 
      
         $my_acf_field = wp_trim_words(get_sub_field('blog_post_text'), 100);
         // break to stop loop
         break;
        endif;
    endwhile;
    else:
    endif;
    reset_rows();
    return $my_acf_field . '' . $excerpt;
}
