Do you perhaps have a lot of modded maps added or did you write a lot of markings on the map?

It looks like the map might have too much info from those maps and errors out with a buffer overflow due to that

Go to C:\Users\YourUserName\Zomboid\Saves\Multiplayer and delete or move the folder with the server name. Then check if the issue persists.
