assigment call,increment,decerment new object expresion can be used as statemnt

 void OnTriggerEnter2D (Collider2D other)
	{
		if (gameObject.tag == "enemy");
		{
			respawnManager.RespawnPlayerCo;
			//this.Player.position = Respawn.position;
		}
	}

}

You have a stray statement that performs nothing.

respawnManager.RespawnPlayerCo;

Do you want to assign something to this variable or you want something to be assigned with this variable?
