Particle system .Play() doesn't seem to want to play the particles.

For some reason it just doesn’t work. I know unity has had issues with this for a while. Checking via Debug.Log and isPlaying, it says False.

Here is the part of the code relevant to it:

// References
    public Animator animator;
    [SerializeField] Transform targetEnemy;
    [SerializeField] ParticleSystem weaponVFX;
    [SerializeField] AudioClip gunShotSound;
    [SerializeField] AudioClip reloadSound;
    [SerializeField] AudioClip emptySound;
    AudioSource audioSource;
    Transform shootingPoint;
    [SerializeField] GameObject equippedWeapon;

    public void EquippedWeaponType(Item item) // We set the weapon type here based on what the player has equipped
    {
        if (item is Weapon weapon)
        {
            switch (weapon.type)
            {
                // We set the weapon stats based on the weapon type
                case Weapon.WeaponType.Handgun:
                case Weapon.WeaponType.Shotgun:
                case Weapon.WeaponType.Rifle:
                    weaponDamage = weapon.weaponDamage;
                    ammoCapacity = weapon.ammoCapacity;
                    reloadSpeed = weapon.reloadSpeed;
                    fireRate = weapon.fireRate;
                    equippedWeaponType = weapon.type;
                    weaponVFX = weapon.weaponVFX;
                    weaponVFX.Stop();
                    equippedWeapon = weapon.model;
                    shootingPoint = equippedWeapon.transform.Find("Shooting Point");
                    gunShotSound = weapon.gunShotSound;
                    reloadSound = weapon.reloadSound;
                    emptySound = weapon.emptySound;
                    isEquipped = true;
                    canShoot = true;
                    Debug.Log(shootingPoint);
                    break;
            }
        }
    }

    IEnumerator HandgunShooting()
    {
        var inventoryUI = InventoryUI.instance;
        var audioManager = AudioManager.instance;
      
        canShoot = false;
        DealDamage();
        handgunMagazine --;
        animator.SetTrigger("Shoot");
        audioSource.PlayOneShot(gunShotSound);
        weaponVFX.Play();
        Debug.Log(weaponVFX.isPlaying);
        //weaponVFX.gameObject.SetActive(true);
        inventoryUI.UpdateUI();
        yield return new WaitForSeconds(fireRate);
        animator.ResetTrigger("Shoot");
        weaponVFX.Stop();
        //weaponVFX.gameObject.SetActive(false);
        canShoot = true;
    }
