ArkNoob5

I'm running on a PC with the Windows Store version of ARK. I set it to run dedicated mode, and all seems well. 3 of us join and we play for 5 or 10 minutes but then Ark on the dedicated server just closes out and crashes back to the desktop. This then causes the game to stop accepting new commands and then the players get a disconnect/server stopped responding error. I can't find any log files, so I'm having trouble seeing what is causing the Ark app to stop working and crash to desktop without any error messages. Does anyone have any suggestions or advice? Thank you
