Can't save order, can't process orders

Here is the process https://akmp.com.ua/1109/ when you try to save the order, it just freezes tightly and nothing happens to it. Errors occur on their own on different orders, but the main thing is that they are constantly repeated, we cannot process such orders normally What needs to be done so that the system does not freeze at such stages, how can this be solved?
