My OnTriggerEnter2D does not work for a snake game.

Questions & Answers
1

The head of the snake has a rigidbody2D and a trigger collider, but nothing happens when the snake collides the wall or its tail.The snake moves by InvokeRepeating a function that changes the position of the snake game object . This kind of problem has never happened before on other projects, does that has something to do with the snake movement?

The script of the boundary:

void OnTriggerEnter2D(Collider2D other)
        {
            if (other.tag == "player")
            {
                Debug.Log("entered");
                Destroy(other.gameObject);
            }
        }

check the isTrigger in collider

Here is the movement script

public class Movement : MonoBehaviour
{
    public GameObject player;
    [HideInInspector] public Vector2 playerPos;
    public GameObject trail;
    public int direction;
    public Vector2 rotation = new Vector2(0, 0);
    public float unit;

    void Start()
    {
        playerPos = player.transform.position;
        InvokeRepeating("Move", 0, 0.055f);
    }

    void Update()
    {
        if (direction != 2 && Input.GetKeyDown(KeyCode.W))
        {
            direction = 1;
        }
        if (direction != 4 && Input.GetKeyDown(KeyCode.A))
        {
            direction = 3;
        }
        if (direction != 3 && Input.GetKeyDown(KeyCode.D))
        {
            direction = 4;
        }
        if (direction != 1 && Input.GetKeyDown(KeyCode.S))
        {
            direction = 2;
        }

    }

    void Move()
    {
        switch (direction)
        {
            case 1:

                playerPos = new Vector2(playerPos.x, playerPos.y + unit);
                player.transform.position = playerPos;
                Instantiate(trail, new Vector2(playerPos.x, playerPos.y - 1), Quaternion.identity);
                break;
            case 2:
                playerPos = new Vector2(playerPos.x, playerPos.y - unit);
                player.transform.position = playerPos;
                Instantiate(trail, new Vector2(playerPos.x, playerPos.y + 1), Quaternion.identity);
                break;
            case 3:
                playerPos = new Vector2(playerPos.x - unit, playerPos.y);

                player.transform.position = playerPos;
                Instantiate(trail, new Vector2(playerPos.x + 1, playerPos.y), Quaternion.identity);
                break;
            case 4:
                playerPos = new Vector2(playerPos.x + unit, playerPos.y);
                player.transform.position = playerPos;
                Instantiate(trail, new Vector2(playerPos.x - 1, playerPos.y), Quaternion.identity);
                break;
        }
    }
