Server Does Not Start: [IPC] Received shutdown signal

Hello. I cannot start an existing server of mine that I've been playing with my gf. I have cloud saves on and nothing special happened the last time we closed the game. Now we get "There was some sort of trouble starting the server. Please try again." and every time we do there is another clone of the most recent save in the rollback tab, pushing out older saves. Rolling back to any previous save has not solved the problem. Neither has turning off mods. We are playing with server and client mods, but they are working fine in my other world, which has the same settings.

I attached the save from the CloudSaves folder and the most recent logs from the overworld and the caves another time for good measure. The only irregularity in comparison to other logs I could find is the "[IPC] Received shutdown signal" line near the end in the overworld log, but there is no indication why the server would be receiving a shutdown signal.

Any help in restoring the save in addition to fixing the bug causing this would be very much appreciated. This is the second save we have lost this year and I am scared to play my worlds or start another world now. We can never get into the late game because the saves get corrupted and don't want to play through the whole early game again just to lose it again.
