Libre Office sporadically won't open new documents. How to overcome?

Question

openoffice

From the outside, the problem can be described as: documents were opened, and then they stopped. OS of the Windows family. Libra's version is unimportant. The problem has been observed since the third open.
When you try to open a document, a new process appears in the task manager, but it does not reach the opening of the editor window. So all sorts of soffice.bin, scalc.exe and other offal hang without any activity.
But it is worth killing the very first process on which everything is hanging, the rest of the waiting processes begin to open windows with documents. Such a deadlock.
It occurs quite rarely, but due to the fact that I have a couple of hundred cars with a libra, no, no, but it pops up.
What to do with it? It's effective to kill processes via taskkill, but it's inconvenient.
