I am also experiencing the same issues as above.
Steps to recreate:
Start game, click "Join Server"
Search for friends server I've previously played on
Connect and type password
At loading of configs the console starts filling up with the above mentioned error
Remediation attempts:
I have verified file integrity, which ended up erroring out due to a file currently being in use during the process.
I then uninstalled and re-installed the game through the Xbox launcher, moving my initial installation from a HDD to an nvme and then attempted to re-join the server.
First time joining I got as far as "Creating Character" and eventually got the "WRN NET LITENETLIB" error again.
Each attempt after, the error started after loading of the configs.
I've asked the admin if he could restart the server and still experience the same issue after a server restart.
Looking in the logs, I see that a remote connection is seemingly dropped, so I've verified there were ports open in my firewall specific to 7D2D.
I have a total of 5 ports available:
Inbound: 4
Two ports reference the .exe of my previous installation and are open to any port for TCP and UDP under the Private profile
Two ports reference the new installation following the same rules
Outbound: 1
Open to any port, any protocol and any profile
Here are my logs, I've redacted my user name only for personal privacy:
