“wp_enqueue_block_style()” function is not called on function.php file.
fixed the error temporarily by removing the function from blocks.php and commenting this lines in index.php file from blocks folder:
//require ABSPATH . WPINC . ‘/blocks/comment-reply-link.php’;
//require ABSPATH . WPINC . ‘/blocks/comment-template.php’;
//require ABSPATH . WPINC . ‘/blocks/query-no-results.php’;
//require ABSPATH . WPINC . ‘/blocks/read-more.php’;
