V Rising server fails to start: Wine UnityPlayer.dll initialization failure

[Mix2-9]

Description

I’m having issues starting the V Rising dedicated server using the Docker image
trueosiris/vrising.

The container pulls and installs the server successfully via SteamCMD, but the
server fails to launch when Wine starts the actual server executable.

The image was pulled on 2026-02-28.
