Client Crash when private server is running on LAN

[Darkwynd 0]

I have a 1x1 grid running on a dedicated server on my LAN. Everything shows to be running 11.4 (106774)

The server appears on the Unofficial server list as expected, but it causes my client to immediately crash.

As soon as remote to the server and close the atlas server, my client no longer crashes, and will allow me to play any other private or official server without trouble.

 

I have tried several combinations of with and without battleye settings on both the server and client, nothing changes. I don't even have to try to JOIN my server, just the fact it is on the list makes the client throw the error.
