I'm also having the issue of my V Rising server looping if BepInEx is set to true. I tried manually placing the files in the directory, but that didn't work. I can launch V Rising with BepInEx installed on my gaming PC, so I don't think it's an issue with BepInEx needing an update, but I'm not sure.
I'm also seeing this. I don't know if it's connect to this. They posted it in the official discord just over an hour ago
"Server Outage Notice:

This is causing connectivity issues with co-op and servers.
Singleplayer is unaffected by this server outage.
We are sorry for this inconvenience and we are working to recover stable operation as soon as possible.
