    In my project I use Addressables, and I am trying to build a dedicated server build to deploy to Multiplay hosting services.

    Build target is Linux OS,build settings are default, scripting backend set to IL2CPP.

    When Addressables.InstantiateAsync() is being called for the first time, a "Graphics device is null" error is firrd and the server crashes. Here are the logs:

    Graphics device is null.

    The server runs in a batchMode, meaning the Launch Parameters are -nographics -batchmode.

    It sounds like a very standard scenario, but I couldn't find any solution anywhere, including approaching the Multiplay support team.

    Can someone shed some light on this?
