Here is my code

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

public class PlayerController : MonoBehaviour
{
    [Header("Horizontal Movement Settings:")]
    [SerializeField] private float WalkSpeed = 1;
    [Space(5)]

    [Header("Vertical Movement Settings")]
    [SerializeField] private float JumpForce = 45;
    [SerializeField] private int JumpBufferFrames;
    [SerializeField] private float CoyoteTime;
    private int JumpBufferCounter = 0;
    private float CoyoteTimeCounter = 0;
    private int AirJumpCounter = 0;
    [SerializeField] private int MaxAirJumps = 1;
    [Space(5)]

    [Header("Dash Settings")]
    [SerializeField] private float DashSpeed;
    [SerializeField] private float DashTime;
    [SerializeField] private float DashCooldown;
    [Space(5)]

    //References
    Rigidbody2D rb;

    }  

    private void OnCollisionEnter2D(Collision2D other)

        {

        else

    IEnumerator Dash() //the dash action the player performs

        anim.SetTrigger("Dashing");
        rb.gravityScale = 0;
        rb.velocity = new Vector2(transform.localScale.x * DashSpeed, 0);
        yield return new WaitForSeconds(DashTime);
        rb.gravityScale = Gravity;
        PState.dashing = false;
        yield return new WaitForSeconds(DashCooldown);
        CanDash = true;
    }
    
    void StartDash()
    {
        if(Input.GetButtonDown("Dash") && CanDash && !Dashed)
        {
            StartCoroutine(Dash());
            Dashed = true;
        }

        if (Grounded == true)
        {
            Dashed = false;
        }
    }
}

I used a different method for the groundcheck in case you’re wondering.

Can you add the highlighted lines below and show me what the Console displays when you dash?

IEnumerator Dash() //the dash action the player performs
{
    CanDash = false;
    PState.dashing = true;
    anim.SetTrigger("Dashing");
    rb.gravityScale = 0;
    rb.velocity = new Vector2(transform.localScale.x * DashSpeed, 0);
    print("Dash coroutine");
    yield return new WaitForSeconds(DashTime);
    rb.gravityScale = Gravity;
    PState.dashing = false;
    print("Dash end");
    yield return new WaitForSeconds(DashCooldown);
    CanDash = true;
    print("Dash cooled down");
}
    
void StartDash()
{
    if(Input.GetButtonDown("Dash") && CanDash && !Dashed)
    {
        print("Dash starting");
        StartCoroutine(Dash());
        Dashed = true;
    }

    if (Grounded == true)
    {
        Dashed = false;
    }
}

Change your private bool canDash; to private bool canDash = true; That should fix it for you. Had the same issue with mine recently.
