Box collider 2d not colliding continuously

Unity Engine
1

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:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class PlayerController : MonoBehaviour {

    [SerializeField]
    private float speed;
    private Vector2 playerVector;
    private Animator animator;
    private Rigidbody2D myRigidBody;
    private Vector2 facingLeft = new Vector2(-0.5f, 0.5f);
    private Vector2 facingRight = new Vector2(0.5f, 0.5f);

    CreateScreenFade blackFade = null;

    [SerializeField]
    private List<Vector2> firstStagePositionList;

    [SerializeField]
    PositionManager positionManager;

    private int currentRoom = 6;
    private bool hasKey = false;
    public bool HasKey { set { hasKey = value; } }
    public int CurrentRoom
    {
        get {
            return currentRoom;
        }
    }
   

    // Use this for initialization
    void Start () {
        playerVector = transform.position;
        animator = GetComponent<Animator>();
        myRigidBody = GetComponent<Rigidbody2D>();
        blackFade = GameObject.Find("CreateBlackScreen").GetComponent<CreateScreenFade>();       
    }
   
    // Update is called once per frame
    void Update () {       
        PlayerMovingLogic();
    }

    private void PlayerMovingLogic( )
    {
        if(!CreateScreenFade.isFading) {           
            playerVector.x = Input.GetAxisRaw("Horizontal");
            playerVector.y = Input.GetAxisRaw("Vertical");
           
            //Player animation logic
            if(playerVector.x > 0.0f || playerVector.x < 0.0f || playerVector.y >0.0f || playerVector.y    < 0.0f) {
                animator.SetBool("Run", true);
            } else {
                animator.SetBool("Run", false);
            }

            //Player Direction logic
            if(playerVector.x  > 0.0f) {
                transform.localScale = facingRight;
            }else if (playerVector.x  < 0.0f) {
                transform.localScale = facingLeft;
            }           
        } else {
            animator.SetBool("Run", false);
        }
    }

    private void MoveCharacter() {
        //myRigidBody.MovePosition(transform.position + playerVector * speed * Time.deltaTime);       
    }

    private void FixedUpdate( )
    {
        myRigidBody.MovePosition(myRigidBody.position + playerVector * speed * Time.fixedDeltaTime);
    }

And also treasure chest code:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class TreasureChest : MonoBehaviour
{
    [SerializeField] GameObject spawnObject;
    private Animator animator;
    private bool isOpened = false;
    // Start is called before the first frame update
    void Start()
    {
        animator = GetComponent<Animator>();
    }

    private void OnCollisionStay2D(Collision2D collision)
    {
        if(collision.gameObject.tag == "Player") {
            Debug.Log("Collide with chest");
            if(Input.GetKeyDown(KeyCode.Space) && !isOpened ) {
                isOpened = true;
                animator.SetBool("Open", true);
                Instantiate(spawnObject, transform.position, Quaternion.identity);
            }
        }
    }

}

Here is the rigidbody2d settings for both

Thank you.
