Player controller jump not always working

Hi, I am relatively new to unity and I am making a game with some friends. We have run into a problem where the player doesn't jump sometimes. I am not sure if it is a Fixed Update() vs Update() problem or something with our colliders. Any advice would really be appreciated. Here is my code

 using UnityEngine;
 using UnityEngine.Events;
 
 public class CharacterController2D : MonoBehaviour
 {
     [SerializeField] private float m_JumpForce = 400f;                            // Amount of force added when the player jumps.
     // [Range(0, 1)] [SerializeField] private float m_CrouchSpeed = .36f;            // Amount of maxSpeed applied to crouching movement. 1 = 100%
     [Range(0, .3f)] [SerializeField] private float m_MovementSmoothing = .05f;    // How much to smooth out the movement
     [SerializeField] private bool m_AirControl = false;                            // Whether or not a player can steer while jumping;
     [SerializeField] private LayerMask m_WhatIsGround;                            // A mask determining what is ground to the character
     [SerializeField] private Transform m_GroundCheck;                            // A position marking where to check if the player is grounded.
     // [SerializeField] private Transform m_CeilingCheck;                            // A position marking where to check for ceilings
     // [SerializeField] private Collider2D m_CrouchDisableCollider;                // A collider that will be disabled when crouching
 
     const float k_GroundedRadius = .3f; // Radius of the overlap circle to determine if grounded
     public bool m_Grounded;            // Whether or not the player is grounded.
     // const float k_CeilingRadius = .2f; // Radius of the overlap circle to determine if the player can stand up
     private Rigidbody2D m_Rigidbody2D;
     private bool m_FacingRight = true;  // For determining which way the player is currently facing.
     private Vector3 m_Velocity = Vector3.zero;
 
     [Header("Events")]
     [Space]
 
     public UnityEvent OnLandEvent;
 
     [System.Serializable]
     public class BoolEvent : UnityEvent<bool> { }
 
     // public BoolEvent OnCrouchEvent;
     // private bool m_wasCrouching = false;
 
     private void Awake()
     {
         m_Rigidbody2D = GetComponent<Rigidbody2D>();
 
         if (OnLandEvent == null)
             OnLandEvent = new UnityEvent();
 
         // if (OnCrouchEvent == null)
         //     OnCrouchEvent = new BoolEvent();
     }
 
     private void FixedUpdate()
     {
         bool wasGrounded = m_Grounded;
         m_Grounded = false;
 
         // The player is grounded if a circlecast to the groundcheck position hits anything designated as ground
         // This can be done using layers instead but Sample Assets will not overwrite your project settings.
         Collider2D[] colliders = Physics2D.OverlapCircleAll(m_GroundCheck.position, k_GroundedRadius, m_WhatIsGround);
         for (int i = 0; i < colliders.Length; i++)
         {
             if (colliders[i].gameObject != gameObject)
             {
                 m_Grounded = true;
                 if (!wasGrounded)
                     OnLandEvent.Invoke();
             }
         }
     }
 
 
     public void Move(float move, bool crouch, bool jump)
     {
     
 
         //only control the player if grounded or airControl is turned on
         if (m_Grounded || m_AirControl)
         {
 
             
 
             // Move the character by finding the target velocity
             Vector3 targetVelocity = new Vector2(move * 10f, m_Rigidbody2D.velocity.y);
             // And then smoothing it out and applying it to the character
             m_Rigidbody2D.velocity = Vector3.SmoothDamp(m_Rigidbody2D.velocity, targetVelocity, ref m_Velocity, m_MovementSmoothing);
 
             // If the input is moving the player right and the player is facing left...
             if (move > 0 && !m_FacingRight)
             {
                 // ... flip the player.
                 Flip();
             }
             // Otherwise if the input is moving the player left and the player is facing right...
             else if (move < 0 && m_FacingRight)
             {
                 // ... flip the player.
                 Flip();
             }
         }
         // If the player should jump...
         if (m_Grounded && jump)
         {
             // Add a vertical force to the player.
             m_Grounded = false;
             m_Rigidbody2D.AddForce(new Vector2(0f, m_JumpForce));
         }
     }
 
 
     private void Flip()
     {
         // Switch the way the player is labelled as facing.
         m_FacingRight = !m_FacingRight;
 
         // Multiply the player's x local scale by -1.
         Vector3 theScale = transform.localScale;
         theScale.x *= -1;
         transform.localScale = theScale;
     }
 }
