Bitrix:sale.order.ajax does not place an order?

Question

1C-Bitrix

How to find an error in the bitrix:sale.order.ajax component I
stopped placing an order after updates, it does not give errors, not in the console, not in php

. Just when sending an order, the preloader spins, then everything disappears. The order is not processed and the redirect does not work.
