Problem. The game \ "crashes \" when trying to save. (Stellaris)

Hello.
Today I discovered that the game began to crash during autosave, as well as when trying to manually save. All this happens in one particular batch, because when creating a new batch, everything works as expected.

Who faced this problem and how was it solved?
PS game - license. patched to 1.1. There are no incompatible mods, there are no lags during the game.
