Animation locks my camera to horizontal only? (Can't look up or down)

Unity Engine

Hey guys

I have a first person camera system that uses a few animations (mainly for moving the item floating above the camera)

All of the animations have been fine up to now, I have made an animation that moves the camera and for some reason it locks my mouse movement to horizontal only. When I get rid of this animation from the Animator controller it works fine.

Here is how I have my hierarchy: Imgur: The magic of the Internet

The animator: https://imgur.com/Mt8uWbB

And finally here is the code I use for my camera just incase: (I have some animations in a different script due to FixedUpdate causing some delay in the animation)

Could someone try and explain why my cameras movement is locked when I have this animation?

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

public class CharacterController : MonoBehaviour
{
    [SerializeField]
    private AudioClip[] clips;
    private AudioSource audioSource;
    private Animator anim;
    public float WalkSpeed = 2.0f;
    private bool OnGround;
    private bool open;

    void Start()
    {
        audioSource = GetComponent<AudioSource>();
        anim = GetComponent<Animator>();
        Cursor.visible = false;
        Cursor.lockState = CursorLockMode.Locked;
        OnGround = false;
        open = false;
    }

    private AudioClip GetRandomClip()
    {
        return clips[UnityEngine.Random.Range(0, clips.Length)];
    }

    // Grabs a random clip and plays the sound each time "step" is called.
    // "step" has an animation event each time the player models foot touches the ground.
    // This  means that step is run every time there is an animation event on player animation.
    // The player has this on his running and walking animations.
    private void Step()
    {
        AudioClip Step = GetRandomClip();
        audioSource.PlayOneShot(Step);
    }

    void OnCollisionStay(Collision other)
    {
        if (other.collider.gameObject.CompareTag("Ground"))
        {
            OnGround = true;
        }
    }

    void OnCollisionExit()
    {
        OnGround = false;
    }

    void FixedUpdate()
    {
        float translation = Input.GetAxis("Vertical") * WalkSpeed;
        float strafe = Input.GetAxis("Horizontal") * WalkSpeed;
        translation *= Time.deltaTime;
        strafe *= Time.deltaTime;
        transform.Translate(strafe, 0, translation);

        if (OnGround)
        {   //movement
            if (Input.GetKey("w") || Input.GetKey("a") || Input.GetKey("d"))
            {
                anim.SetBool("isWalking", true);
                anim.SetBool("isJumping", false);
            }
            else
            {
                anim.SetBool("isWalking", false);
            }

            // sprinting
            if (Input.GetKey("left shift") && (Input.GetKey("w") && anim.GetBool("isCrouching") == false && anim.GetBool("isCrouchWalk") == false))
            {
                anim.speed = 1.7f;
                WalkSpeed = 3.5f;

                if (Input.GetKey("a") || (Input.GetKey("d")))
                {
                    WalkSpeed = 2.5f;
                }
            }
            else
            {
                anim.speed = 1.0f;
                WalkSpeed = 2.0f;

                if (Input.GetKey("s"))
                {
                    WalkSpeed = 1.0f;
                    anim.SetBool("isWalking", true);
                }
            }

            //jump related
            if (Input.GetKey("w") && Input.GetKey("space"))
            {
                anim.SetBool("isWalking", false);
                anim.SetBool("isJumping", true);
                anim.speed = 1.0f;

            }
            if (Input.GetKey("w") && Input.GetKey("space") && Input.GetKey("left shift"))
            {
                anim.SetBool("isWalking", false);
                anim.SetBool("isJumping", true);
                anim.speed = 1.0f;
            }
        }
    }
}

Okay I figured out the problem for anyone else who may have this problem.

I needed to have my Y mouse movement in the LateUpdate function. I created a bool which turned on/off when I pressed tab. When enabled it turned the LateUpdate function on with my Y mouse movement inside. While off it used the normal Y movement in the regular update function.

 public void LateUpdate()
    {
        if (!isAnimationControllingCamera)
        {
            transform.localRotation = Quaternion.AngleAxis(-mouseLook.y, Vector3.right);
        }
    }
