Box collider 2d not colliding continuously

I am making a top down rpg game. There are two game objects which is my character and a treasure box. Both have box collider 2d attached to them. The problem I am having is OnCollisionStay2D only happened if I keep pressing right, even though the colliders are colliding with each other. I expected it to stay colliding. Below is my code for my character:

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class PlayerController : MonoBehaviour {
6.  
7.     [SerializeField]
8.     private float speed;
9.     private Vector2 playerVector;
10.     private Animator animator;
11.     private Rigidbody2D myRigidBody;
12.     private Vector2 facingLeft = new Vector2(-0.5f, 0.5f);
13.     private Vector2 facingRight = new Vector2(0.5f, 0.5f);
14.  
15.     CreateScreenFade blackFade = null;
16.  
17.     [SerializeField]
18.     private List<Vector2> firstStagePositionList;
19.  
20.     [SerializeField]
21.     PositionManager positionManager;
22.  
23.     private int currentRoom = 6;
24.     private bool hasKey = false;
25.     public bool HasKey { set { hasKey = value; } }
26.     public int CurrentRoom
27.     {
28.         get {
29.             return currentRoom;
30.         }
31.     }
32.    
33.  
34.     // Use this for initialization
35.     void Start () {
36.         playerVector = transform.position;
37.         animator = GetComponent<Animator>();
38.         myRigidBody = GetComponent<Rigidbody2D>();
39.         blackFade = GameObject.Find("CreateBlackScreen").GetComponent<CreateScreenFade>();      
40.     }
41.    
42.     // Update is called once per frame
43.     void Update () {      
44.         PlayerMovingLogic();
45.     }
46.  
47.     private void PlayerMovingLogic( )
48.     {
49.         if(!CreateScreenFade.isFading) {          
50.             playerVector.x = Input.GetAxisRaw("Horizontal");
51.             playerVector.y = Input.GetAxisRaw("Vertical");
52.            
53.             //Player animation logic
54.             if(playerVector.x > 0.0f || playerVector.x < 0.0f || playerVector.y >0.0f || playerVector.y    < 0.0f) {
55.                 animator.SetBool("Run", true);
56.             } else {
57.                 animator.SetBool("Run", false);
58.             }
59.  
60.             //Player Direction logic
61.             if(playerVector.x  > 0.0f) {
62.                 transform.localScale = facingRight;
63.             }else if (playerVector.x  < 0.0f) {
64.                 transform.localScale = facingLeft;
65.             }          
66.         } else {
67.             animator.SetBool("Run", false);
68.         }
69.     }
70.  
71.     private void MoveCharacter() {
72.         //myRigidBody.MovePosition(transform.position + playerVector * speed * Time.deltaTime);      
73.     }
74.  
75.     private void FixedUpdate( )
76.     {
77.         myRigidBody.MovePosition(myRigidBody.position + playerVector * speed * Time.fixedDeltaTime);
78.     }
79.  

And also treasure chest code:

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class TreasureChest : MonoBehaviour
6. {
7.     [SerializeField] GameObject spawnObject;
8.     private Animator animator;
9.     private bool isOpened = false;
10.     // Start is called before the first frame update
11.     void Start()
12.     {
13.         animator = GetComponent<Animator>();
14.     }
15.  
16.     private void OnCollisionStay2D(Collision2D collision)
17.     {
18.         if(collision.gameObject.tag == "Player") {
19.             Debug.Log("Collide with chest");
20.             if(Input.GetKeyDown(KeyCode.Space) && !isOpened ) {
21.                 isOpened = true;
22.                 animator.SetBool("Open", true);
23.                 Instantiate(spawnObject, transform.position, Quaternion.identity);
24.             }
25.         }
26.     }
27.  
28. }
29.  

Here is the rigidbody2d settings for both




Thank you.
