I have exact same issue. Smaller map file unpacked, .exe run as administrator, terminal opened and closed. Upon starting MSFS CMD windows opens but there is no map with "terrain" on and after some time CMD windows closes itself. Mod with .bat file posted by other user above keeps CMD window up by also no map showing anyway. Someone told that bigger map file (11 GB) solves the issue but I won't be able to test it, as the server it's uploaded to require 50 hours to download this file (80 KB/s transfer...). I can't even delete map-server folder as I don't have rar file anymore to replace it and even smaller version takes 6 hours to redownload. EDIT: I now see "map-server.exe" is trying to write into some default pathing on C: while I have MSFS24 installed on other drive. Can this be the reason?
