Product order problem

Good day.

I would ask for advice. Something happened to us taking orders.

Everything is OK when creating the order. I will come to the payment, I will pay everything OK. The customer pays, the money for paypal comes to me. The problem occurs - the customer's product still remains in the shopping cart (as if he did not pay for it at all) A new customer is not created in the administration, no e-mail is sent and the order is not displayed in the TODO list either. I don't know why it stopped working. The last time I tested it was on version 8.6.13 (everything was ok) I currently have version 8.6.14. (restart, database optimization via panel did not help) I will be grateful for any advice.
