Why doesn't moving an object work in Unity?

Question

C++ / C#

There is an object (player) with Rigidbody2d, BoxCollider2d on it, there is another object (platform) with BoxCollider2d on it. The following code hangs on the player: Why doesn't the player jump when pressing the space bar? Is there a bug in the code or something in the editor is off? help me please

using System.Collections; 
using System.Collections.Generic; 
using UnityEngine; 
 
public class Move : MonoBehaviour 
{ 
 Rigidbody2D rb; 
 
 void Start() 
 { 
  rb = GetComponent<Rigidbody2D> (); 
 } 
 
 void Update() 
 { 
 if (Input.GetKeyDown (KeyCode.Space)) 
  { 
   jump(); 
  } 
 } 
 
 void jump() 
 { 
  rb.AddForce(transform.up * 14f, ForceMode2D.Impulse); 
 } 
}

Try to poke the Rigidbody2d settings - quite by accident, physics can be turned off there altogether or specifically gravity physics. If it doesn’t help, find a standard unity asset with a 2d robot (inside the unit, right-click in the assets - package import - characters (characters)), the movement is fully implemented there (but unfortunately, it’s made too abstruse and it can be hard to disassemble it, but it works )
