ITriggerJob causes a crash after scene reload

so I have this triggerJob in my game. When I start the game the Job works fine but after the scene resets, that job causes my game to just stop working.

Code (CSharp):

1. public class triggerWithPlayerSystem : JobComponentSystem
2. {
3.     [BurstCompile]
4.     public struct PlayerOnTriggerJob : ITriggerEventsJob
5.     {
6.         [ReadOnly]
7.         public ComponentDataFromEntity<playerData> playerEntity;
8.  
9.         public ComponentDataFromEntity<triggerComponent> triggerEntity;
10.  
11.         public void Execute(TriggerEvent triggerEvent)
12.         {
13.             if (playerEntity.HasComponent(triggerEvent.Entities.EntityA))
14.             {
15.                 if (triggerEntity.HasComponent(triggerEvent.Entities.EntityB))
16.                 {
17.                     triggerComponent trigger = triggerEntity[triggerEvent.Entities.EntityB];
18.                     trigger.active = true;
19.                     triggerEntity[triggerEvent.Entities.EntityB] = trigger;
20.                 }
21.             }
22.  
23.             if (playerEntity.HasComponent(triggerEvent.Entities.EntityB))
24.             {
25.                 if (triggerEntity.HasComponent(triggerEvent.Entities.EntityA))
26.                 {
27.                     triggerComponent trigger = triggerEntity[triggerEvent.Entities.EntityB];
28.                     trigger.active = true;
29.                     triggerEntity[triggerEvent.Entities.EntityB] = trigger;
30.                 }
31.             }
32.         }
33.     }
34.  
35.     private BuildPhysicsWorld buildPhysicsWorld;
36.     private StepPhysicsWorld stepPhysicsWorld;
37.  
38.     protected override void OnCreate()
39.     {
40.         if(buildPhysicsWorld == null)
41.             buildPhysicsWorld = World.GetOrCreateSystem<BuildPhysicsWorld>();
42.  
43.         if (stepPhysicsWorld == null)
44.             stepPhysicsWorld = World.GetOrCreateSystem<StepPhysicsWorld>();
45.     }
46.  
47.     protected override JobHandle OnUpdate(JobHandle inputDeps)
48.     {
49.         PlayerOnTriggerJob job = new PlayerOnTriggerJob
50.         {
51.             playerEntity = GetComponentDataFromEntity<playerData>(isReadOnly: true),
52.             triggerEntity = GetComponentDataFromEntity<triggerComponent>(),
53.         };
54.  
55.         return job.Schedule(stepPhysicsWorld.Simulation, ref buildPhysicsWorld.PhysicsWorld, inputDeps);
56.     }
57. }
58.  

any reason why?
