Unity 2D Not detecting when touching object with tag obstacle

Question

I am making a game similar to flappy bird I am currently following this guy's tutorial and I'm stuck near the end I have been searching for 4hours and can't find a solution here's the code

Game Manager:

using UnityEngine;

public class GameManager : MonoBehaviour
{
    private int score;

    public void GameOver()
    {
        Debug.Log("Game Over!");
    }

    public void IncreaseScore()
    {
        score++;
    }
}

player:

using UnityEngine;

public class playermove : MonoBehaviour
{
    private Vector3 direction;

    public float gravity = -9.8f;
    public float strength = 5f;

    private void Update()
    {
        if (Input.GetKeyDown(KeyCode.Space) || Input.GetMouseButtonDown(0))
        {
            direction = Vector3.up * strength;
        }

        direction.y += gravity * Time.deltaTime;
        transform.position += direction * Time.deltaTime;
    }

    private void OnTriggerEnter2D(Collider2D other)
    {
        if (other.gameObject.tag == "Obstacle")
        {
            FindObjectOfType<GameManager>().GameOver();
        } else if (other.gameObject.tag == "Score")
        {
            FindObjectOfType<GameManager>().IncreaseScore();
        }
    }

}

I'm trying to detect when the player hits a sprite with a tag and 2d collider (set as a trigger) edit: Inspector ss of trigger object
