Unable to load server: Could not load file or assembly 'Sandbox.Game'

[daantimmer]

I've created a TestInstance (yes I did), using the Space Engineers Dedicated Server. Copied the TestInstance folder to where I'll be creating the container from, started it, and then I get the following:

PS E:\Space Engineers Docker Server> docker compose up

This is my directory tree:

And this is the DedicatedServer64 contents, which clearly contains Sandbox.Game.dll:

Please advice :-)
