This solved the problem:
/woo-order-splitter/inc/wos-essentials.php Line 37

                  if (is_object($order)) {
                            if (!$order->customer_id > 0){
                                    $order = $order_id;
                            }
                    } else {
                            if (is_numeric($order_id)) {
                                    $oder = $order_id;
                            }
                    }

I have now set the memory as follows, but the problem persists
define(‘WP_MEMORY_LIMIT’, ‘1024M’);
define(‘WP_MAX_MEMORY_LIMIT’, ‘1536M’);

Here’s the screenshot because I couldn’t include it in the post earlier
