How do I get my CharacterController to Slide? (then crawl when it stops)

I’m making a game where you can press “q” to slide when you’re at a certain speed. If you’re too slow, or when you eventually slow down from the slide, you start “crawling” (moving slow). I can make the CharacterController crawl, but I can’t make it slide (it seems to just reverse your controls while crawling).
This is my code.

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

public class PlayerMovement : MonoBehaviour
{
    public CharacterController controller;

    public float speed = 12f;
    public float crawlSpeed = 0f;
    public float gravity = -9.81f;
    public float jumpHeight = 3f;
    public float crouchHeight = 0.5f;
    public float slideDuration = 1f;

    public Transform groundCheck;
    public float groundDistance = 0.4f;
    public LayerMask groundMask;

    private float slideMinus;
    private float pSpeed;
    private float speedBackup;
    private Vector3 scaleBackup;
    private Vector3 move2;

    Vector3 velocity;
    bool isGrounded;

    private void Start()
    {
        print(transform.right);
        print(transform.forward);
        pSpeed = speed;
        speedBackup = speed;
        scaleBackup = transform.localScale;
    }

    // Update is called once per frame
    void Update()
    {
        if(Input.GetKey("q") == false)
        {
            transform.localScale = scaleBackup;
        }

        pSpeed = speedBackup;

        isGrounded = Physics.CheckSphere(groundCheck.position, groundDistance, groundMask);

        if(isGrounded && velocity.y < 0)
        {
            velocity.y = -5f;
        }

        float x = Input.GetAxis("Horizontal");
        float z = Input.GetAxis("Vertical");

        Vector3 move = transform.right * x + transform.forward * z;
        move2 = move;

        if(Input.GetKey("q"))
        {
            StartCoroutine("Slide");

            pSpeed = crawlSpeed;

            Crouch();
        }

      
        controller.Move(move * pSpeed * Time.deltaTime);
      

        if (Input.GetButtonDown("Jump") && isGrounded)
        {
            velocity.y = Mathf.Sqrt(jumpHeight * -5f * gravity);
        }

        velocity.y += gravity * Time.deltaTime;

        controller.Move(velocity * Time.deltaTime);
    }

    void Crouch()
    {
        transform.localScale = new Vector3(transform.localScale.x, crouchHeight, transform.localScale.z);
    }

    IEnumerator Slide()
    {
        Vector3 moveLocked = move2 * pSpeed * Time.deltaTime;
        controller.Move(new Vector3(moveLocked.x * -0.5f, moveLocked.y, moveLocked.z * -0.5f));
        yield return new WaitForSeconds(1);
    }
}

Any idea how to fix this?

NOTE: I’m a beginner to Unity.
