Resolved Build success but .exe crash?!

So i have the most simple scene you can possibly have:


PS: The terrain is the only element converted to entity

Spoiler: Terrain

No Script (except convert to entity)

No Error OnPlayMode
No Error on Build

But when executing the exe, it just crash?!?!?!
Build Settings:

Spoiler: Build Settings

I tried everything, tweaks conversion settings in every way possible, but i don't get how a scene that simple can crash?

Spoiler: Conversion Settings

 

For reason i can't explain using Latios Bootsrap Does solve the issue?!

Spoiler: Latios Bootsrap i Use

Code (CSharp):

1.     [UnityEngine.Scripting.Preserve]
2.     public class LatiosConversionBootstrap : ICustomConversionBootstrap
3.     {
4.         public bool InitializeConversion(World conversionWorldWithGroupsAndMappingSystems, CustomConversionSettings settings, ref List<Type> filteredSystems)
5.         {
6.             GameObjectConversionGroup defaultGroup = conversionWorldWithGroupsAndMappingSystems.GetExistingSystem<GameObjectConversionGroup>();
7.             BootstrapTools.InjectSystems(filteredSystems, conversionWorldWithGroupsAndMappingSystems, defaultGroup);
8.  
9.             Latios.Psyshock.Authoring.PsyshockConversionBootstrap.InstallLegacyColliderConversion(conversionWorldWithGroupsAndMappingSystems);
10.             Latios.Kinemation.Authoring.KinemationConversionBootstrap.InstallKinemationConversion(conversionWorldWithGroupsAndMappingSystems);
11.             return true;
12.         }
13.     }
14.  
15.     [UnityEngine.Scripting.Preserve]
16.     public class LatiosBootstrap : ICustomBootstrap
17.     {
18.         public unsafe bool Initialize(string defaultWorldName)
19.         {
20.             LatiosWorld world = new LatiosWorld(defaultWorldName);
21.             World.DefaultGameObjectInjectionWorld = world;
22.  
23.             List<Type> systems = new List<Type>(DefaultWorldInitialization.GetAllSystems(WorldSystemFilterFlags.Default));
24.             BootstrapTools.InjectSystems(systems, world, world.simulationSystemGroup);
25.  
26.             CoreBootstrap.InstallImprovedTransforms(world);
27.             Latios.Myri.MyriBootstrap.InstallMyri(world);
28.             Latios.Kinemation.KinemationBootstrap.InstallKinemation(world);
29.  
30.             world.initializationSystemGroup.SortSystems();
31.             world.simulationSystemGroup.SortSystems();
32.             world.presentationSystemGroup.SortSystems();
33.  
34.             ScriptBehaviourUpdateOrder.AppendWorldToCurrentPlayerLoop(world);
35.             return true;
36.         }
37.     }

Still investigating but seems the default world/systems are the issue?

 

Please at least attach the crash log. It's impossible to diagnose the crash without it.

You shouldn't be using the Build Settings window for building your project when using ECS. See the instructions here:
https://docs.unity3d.com/Packages/com.unity.entities@0.51/manual/ecs_building_projects.html

...wait, WHAT?
I'm hitting this error trying unity 2021+ without anything imported other than entities. I've never followed this setup. I'll do so asap to see if I royaly oopsied here but...why now? I've just been using the normal build options.

Unfortunately I'm remote atm so can't provide valid data but it's that straight forward. Install unity 2021.x (HDRP), import entities & build. Success without error, exe crashes on launch no real mentions of why in dump. I can upload later tho...

 

If you are using entities before 1.0.0 you can’t use the normal unity build options you need to use the custom build setup for entities.

if you do want to use the default unity build you need to use the editor 2022.x (currently in beta) and entities 1.0

 

That's incorrect. Before 1.0 you need build options if you using SubScenes (which most of users don't use) otherwise you can build through normal pipeline without issues (Win which is his case because of exe). Our game built through classic pipeline without issues since the beginning up to 1.0

 

If Entities were built prior to 1.0.0 via build settings - resource catalog won't be built, hence causing an exception upon bootstrap, when its been called into.

Subscenes features won't be available in this case, and as for the exception handling - depends on the platform.

Android / iOS it just crashes on launch in release mode.
Dev throws an exception into native log & runs fine.

Standalone PC - throws an exception to the log and I assume runs fine if subscenes not used (for development build) and will crash as well in release.

If you're using a custom bootstrap, its possible to run without subscenes / conversion.
That's what I've did prior to 1.0.0.

 

Ah, nvm thanks for the responses everyone. I'm back on track now, I think -

If anyone else finds themselves behind the times as I have try this link & downloadable project, reviewing their files and structure pointed me in the right direction. Im able to build now:
