So basically my character can't move while I jump or I am in the action of jumping while the scene resets so if the scene resets while I'm jumping the character can't move. also the character gets stuck and cant jump in corners between walls and the floor.

Please help me fix this and I will provide the code so thank you for even attempting to help me all help is appreciated.

Here's my code:

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

 public class PlayerMovementSteamDeck : MonoBehaviour
 {
     [Header("Movement Settings")]
     public float moveSpeed = 5f;
     public float jumpForce = 10f;

     [Header("Ground Check Settings")]
     // The point from which the check will be performed
     public Transform groundCheck;
     // Width of the rectangular ground check area (modifiable)
     public float checkWidth = 0.5f;
     // Fixed height for the ground check area (y-axis remains constant)
     private const float fixedCheckHeight = 0.2f;
     // Which layers count as ground
     public LayerMask groundLayer;
     // Coyote time allows a brief jump after leaving a platform
     public float coyoteTime = 0.2f;
     private float coyoteTimeCounter;

     private bool isGrounded;
     private bool jumpHeld;

     private Rigidbody2D rb;
     private Animator anim;

     void Start()
     {
         rb = GetComponent<Rigidbody2D>();
         anim = GetComponent<Animator>();
     }

     void Update()
     {
         // Update the horizontal movement
         Move();

         // Update the jump input (A button for jumping on Steam Deck)
         jumpHeld = Input.GetButton("Jump");

         // Update ground check via BoxCast
         CheckGround();

         // Update animations
         UpdateAnimations();
     }

     void FixedUpdate()
     {
         // Allow jumping if jump is held and player is grounded or within coyote time
         if (jumpHeld && (isGrounded || coyoteTimeCounter > 0))
         {
             Jump();
         }
     }

     void Move()
     {
         // Get joystick input for Steam Deck
         float moveInput = Input.GetAxisRaw("Horizontal"); // Using raw input for instant 
 response

         // Check if both A and D keys or both Left and Right arrow keys are pressed
         bool aPressed = Input.GetKey(KeyCode.A);
         bool dPressed = Input.GetKey(KeyCode.D);
         bool leftArrowPressed = Input.GetKey(KeyCode.LeftArrow);
         bool rightArrowPressed = Input.GetKey(KeyCode.RightArrow);

         if ((aPressed && dPressed) || (leftArrowPressed && rightArrowPressed))
         {
             moveInput = 0; // Prevent movement if both keys are pressed
         }
         else if (aPressed || leftArrowPressed)
         {
             moveInput = -1; // Move left when only A or Left Arrow is pressed
         }
         else if (dPressed || rightArrowPressed)
         {
             moveInput = 1; // Move right when only D or Right Arrow is pressed
         }

         // Apply movement or stop sliding
         if (moveInput == 0)
         {
             rb.velocity = new Vector2(0, rb.velocity.y); // Stop horizontal movement to 
 prevent sliding
         }
         else
         {
             rb.velocity = new Vector2(moveInput * moveSpeed, rb.velocity.y); // Move 
 player
             transform.localScale = new Vector3(Mathf.Sign(moveInput), 1, 1); // Flip 
 character to face direction of movement
         }
     }

     void Jump()
     {
         rb.velocity = new Vector2(rb.velocity.x, jumpForce);
         // After jumping, reset ground-related flags
         isGrounded = false;
         coyoteTimeCounter = 0f;
     }

     void CheckGround()
     {
         // Define the size of the box for checking
         Vector2 boxSize = new Vector2(checkWidth, fixedCheckHeight);
         // Use a BoxCast downward with zero distance to get collision info including the 
 surface normal
         RaycastHit2D hit = Physics2D.BoxCast(groundCheck.position, boxSize, 0f, 
 Vector2.down, 0f, groundLayer);
         // Only consider the surface as ground if the normal is mostly upward
         if (hit.collider != null && hit.normal.y > 0.7f)
         {
             isGrounded = true;
             coyoteTimeCounter = coyoteTime;  // Reset coyote time when on ground
         }
         else
         {
             isGrounded = false;
             coyoteTimeCounter -= Time.deltaTime;
         }
     }

     void UpdateAnimations()
     {
         anim.SetFloat("Speed", Mathf.Abs(rb.velocity.x));
         // The character is considered jumping if not grounded and coyote time has elapsed
         anim.SetBool("isJumping", !isGrounded && coyoteTimeCounter <= 0);
     }

     // Draw a gizmo in the Scene view to visualize the ground check rectangle
     private void OnDrawGizmosSelected()
     {
         if (groundCheck != null)
         {
             Gizmos.color = Color.red;
             Vector2 boxSize = new Vector2(checkWidth, fixedCheckHeight);
             Gizmos.DrawWireCube(groundCheck.position, boxSize);
         }
     }
 }

also here is the scene reset code for the spikes:

using UnityEngine;
using UnityEngine.SceneManagement;

public class KillZone : MonoBehaviour
{
    private void OnTriggerEnter2D(Collider2D other)
    {
        // Check if the object that entered the trigger has the tag "Player"
        if (other.CompareTag("Player"))
        {
            // Reset the scene instantly
            SceneManager.LoadScene(SceneManager.GetActiveScene().buildIndex);
        }
    }
}
