    i'd solved

    add_action( 'before_delete_post', 'wps_remove_attachment_with_post', 10 );
function wps_remove_attachment_with_post( $post_id ) {

global $post;
$post_type = get_post_type( $post_id );
    if ( $post_type == '<post_type_slug>') {
        
        $gallery = array();
        $meta = get_post_meta( $post_id, '<cpt_metafield>', true );
        $gallery = explode( ',', $meta );
        
        foreach ( $gallery as $img_id ) {
            echo wp_get_attachment_image( $img_id );
            wp_delete_attachment( $img_id, true );
        }
   }
}

    You would be using the delete_post hook, which fires right before a post gets deleted (so you still have access to it). Inside your function, which then fires, you’d fetch all attachments (or attachment IDs) and remove them using wp_delete_attachment.

    add_action( 'delete_post', 'delete_attachments_with_posts', 10, 2 );
function delete_attachments_with_posts( $post_id, $post ) {
    if ( $post->post_type == 'post' ) {
        $attachments = get_posts( array(
            'post_type' => 'attachment',
            'posts_per_page' => -1,
            'post_status' => 'any',
            'post_parent' => $post_id
        ) );
        foreach ( $attachments as $attachment ) {
            wp_delete_attachment( $attachment->ID, true );
        }
    }
}
