For some reason, when I type "stop" in the server console (I am on ubuntu), it says quitting server, then "corrupted double-linked list". I cannot continue to stop the server, nor can i start it back up. I cannot connect to it in minecraft either. This wasn't happening till the update to 1.18.12. It makes it impossible to do anything with the server. I have deleted the entire server and restarted from scratch 5 times, and nothing changes.
