    in il2cpp, there is no server world created
    ie. calling this
    Code (CSharp):
    1. for (int i = 0; i < World.All.Count; i++) {
    2.     var world = World.All[i];
    3.     if (world.GetExistingSystem<ServerSimulationSystemGroup>() != null) {
    4.         return world;
    5.     }
    6. }
    7.  
    8. Debug.LogError($"no server world, count: {World.All.Count}");
    9. return null;
    cannot find the world. (called from a monobehaviour start method)
    no other error is given or reason as to why it fail to initialize
    not sure what to do or how to debug the problem

    There is a bug in netcode 0.6 where the bootstrap can be stripped in some build configurations because it is missing the `Preserve` attribute. Not sure if that is causing this specific issue, but if it is you should be able to work around it by adding something like this to your project
    Code (CSharp):
    1. [UnityEngine.Scripting.Preserve]
    2. public class MyCustomNetCodeBootstrap : ClientServerBootstrap
    3. {
    4.     public override bool Initialize(string defaultWorldName)
    5.     {
    6.         return base.Initialize(defaultWorldName);
    7.     }
    8. }
    Or just add that preserve attribute to your existing custom bootstrap instead if you have one.
