Load/unload scene

unity 2019.2/project tiny 0.16.1

im use SceneService.LoadSceneAsync(request.TargetScene); to load scene
and SceneService.UnloadAllSceneInstances(request.SceneToUnload);

but if i unload scene on button click, app stuck (not crash, log empty after click)
app stuck only if button by which im click locate in same scene which im unload

 

I found solution, here is my code scene manager

Code (CSharp):

1.  
2. using Unity.Entities;
3. using Unity.Tiny.Core;
4. using Unity.Tiny.Scenes;
5.  
6. namespace TemplateTinyProject
7. {
8.     public class LoadSceneTransitionSystem : ComponentSystem
9.     {
10.         private Entity requestEntity;
11.         private LoadSceneTransitionRequest request;
12.         private TinyEnvironment environment;
13.  
14.         protected override void OnCreate()
15.         {
16.             environment = World.TinyEnvironment();
17.             base.OnCreate();
18.         }
19.  
20.         protected override void OnUpdate()
21.         {
22.             requestEntity = Entity.Null;
23.             request = LoadSceneTransitionRequest.Null;
24.  
25.             CurrentLoadedScene currentLoadedScene = environment.GetConfigData<CurrentLoadedScene>();
26.             Entities.ForEach((Entity entity, ref LoadSceneTransitionRequest request) => {
27.                 if (this.request.Equals(LoadSceneTransitionRequest.Null) && !request.Equals(LoadSceneTransitionRequest.Null)) {
28.                     this.request = request;
29.                     this.requestEntity = entity;
30.                 }
31.             });
32.  
33.             if (!request.Equals(LoadSceneTransitionRequest.Null)) {
34.                 //if current scene is null or current scene not qual target scene we load new scene
35.                 if (currentLoadedScene.SceneEntity.Equals(Entity.Null) || (!currentLoadedScene.SceneEntity.Equals(Entity.Null) && !currentLoadedScene.SceneReference.Equals(request.TargetScene))) {
36.                     Entity newScene = SceneService.LoadSceneAsync(request.TargetScene);
37.  
38.                     if (currentLoadedScene.SceneEntity != Entity.Null) {
39.                         SceneService.UnloadAllSceneInstances(currentLoadedScene.SceneEntity);
40.                     }
41.  
42.                     environment.SetConfigData(new CurrentLoadedScene() {
43.                         SceneEntity = newScene,
44.                         SceneReference = request.TargetScene
45.                     });
46.                 }
47.             }
48.  
49.             if (requestEntity != Entity.Null && EntityManager.Exists(requestEntity)) {
50.                 EntityManager.DestroyEntity(requestEntity);
51.             }
52.         }
53.     }
54. }
55.  

Code (CSharp):

1.  
2. using System;

15.         };
16.         public static LoadSceneTransitionRequest Null {
17.             get {
18.                 return @null;
19.             }
20.         }
21.  
22.         public override bool Equals(object obj)
23.         {
24.             return Equals((LoadSceneTransitionRequest)obj);
25.         }
26.  
27.         public bool Equals(LoadSceneTransitionRequest other)
28.         {
29.             return TargetScene.SceneGuid.Equals(other.TargetScene.SceneGuid);
30.         }
31.  
32.         public override int GetHashCode()
33.         {
34.             var hashCode = 710859412;
35.             hashCode = hashCode * -1521134295 + EqualityComparer<SceneReference>.Default.GetHashCode(TargetScene);
36.             return hashCode;
37.         }
