I guess you must be experiencing something similar to what is described on Fourth Fatal Server Crash in 2 days - same error each time - #32 by NetRaven
Not much I can do on my side, I’m only maintaining the Launcher tool.
I would suggest people managing their own server to join the Admins United: Conan Discord server, where you can easily ask questions, and often quickly get suggestions on how to fix issues.
Hopefully the issue will be found and fix soon, but unfortunately it seems to be quite random from what I see.
