Character in game not jumping even though script works on other games with different characters

Hi, I am currently struggling to find a solution with my character not being able to jump in my game. The code which I have used has been used in other games which I have created and work fine on all of them.

The objects which I have on my character are a sprite renderer, box collider 2D, Rigidbody 2D, and of course the script in order for the character to move. I have also tried adding on an animator to see if that would work but it either doesn't affect the character at all or it completely leaves it motionless. I have also tried deleting the character and re doing everything to see if it was just a simple mistake that I had done.

Below is the code which I used:

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

public class Player : MonoBehaviour {

 private Rigidbody2D myRigidBody;
 private float canJumpVect;
 private bool canJump;


 [SerializeField]
 private float movementSpeed;
 private bool facingRight;
 public float thrust;
 public static bool Grounded;


 void Start () {
 
     facingRight = true;
     myRigidBody = GetComponent<Rigidbody2D>();
 }

 void Update () {

     canJumpVect = myRigidBody.transform.position.x;
     if (canJumpVect < -5.134499f) {
         canJump = false;
     } else {
         canJump = true;
     }

     float horizontal = Input.GetAxis ("Horizontal");
     //Debug.Log(horizontal);

     // float vertical = Input.GetAxis("Vertical");

     handleMovement (horizontal);


     Flip(horizontal);


     if (Input.GetKeyDown(KeyCode.Space) && Grounded == true) {
         Debug.Log("jumped");
             if (canJump == true) {
             myRigidBody.AddForce (transform.up * thrust);
             Grounded = false;

         }
     }
 }
 
 
 
 private void handleMovement(float horizontal) {

     myRigidBody.velocity = new Vector2 (horizontal * movementSpeed, myRigidBody.velocity.y);

 }

 private void Flip (float horizontal) {

     if (horizontal > 0 && !facingRight || horizontal < 0 && facingRight) {

         facingRight = !facingRight;

         Vector3 theScale = transform.localScale;

         theScale.x *= -1;

         transform.localScale = theScale;



     }
 }

}

Thank you in advance and I hope that someone will be able to help!
