No way to stop them dude. Hope for updates with bug fixes. Also some events cause the crashes try to detect and avoid them (for me it's being defeated in a battle, which is very weird to be honest)

For me it used to be when I clicked on ships for movement or clicked to move them into a port. At some point the crashes just stopped. Don't know if it was a game update or a driver update.
