Unity Photon2 MissingReferenceExceptionというエラーが出る

Question

エラー
MissingReferenceException: The object of type 'PhotonView' has been destroyed but you are still trying to access it.
Your script should either check if it is null or you should not destroy the object.

注意マーク
PUN is in development mode (development build). As the 'dev region' is not empty (jp) it overrides the found best region. See PhotonServerSettings.

上記のエラーと注意マークが出て困っています。Photon2関係のスクリプトはいじっていないのでエラーで示されているスクリプトは関係がないと自分は思っているのですが、載せないと分からない場合はご指摘お願いいたします。
また、実際に起きている問題としては以下のように片方のプレイヤーが落ちたり、元の位置に戻ったりが繰り返されます。

原因のプログラム

破棄されたゲームオブジェクトを格納した変数を参照している際に出るエラーです。
どこでエラーが発生しているかが書かれていないため、どこを変更すればいいのかは分かりません。

Answer 1

CharacterControllerではなくRigidbodyを使ってプレイヤーを動かすスクリプトに変更したら解決しました。

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using Photon.Pun;

namespace Test
{

    public class Player : MonoBehaviourPunCallbacks
    {
        public float speed;
        public float runModifier;
        public Camera normalCam;
        public GameObject CameraParent;
        public float jumpForce;
        public Transform groundDetector;
        public LayerMask ground;
        private Animator animator;
        private Rigidbody rig;
        //camera
        public float mouseSensitivity = 100f;
        public Transform playerBody;
        float xRotation = 0f;
        [SerializeField]
        private Transform spine;
        
        private void Start()
        {
            rig = GetComponent<Rigidbody>();
            animator = GetComponent<Animator>();
            Cursor.visible = false;
            Cursor.lockState = CursorLockMode.Locked;
            CameraParent.SetActive(photonView.IsMine);
            if (!photonView.IsMine)
            {
                gameObject.layer = 9;
            }
        }
        private void FixedUpdate()
        {
            if (!photonView.IsMine) return;
            if (Input.GetKeyDown(KeyCode.Escape))
            {
                Cursor.visible = true;
                Cursor.lockState = CursorLockMode.None;
            }
            //Axies
            float move_h = Input.GetAxisRaw("Horizontal");
            float move_v = Input.GetAxisRaw("Vertical");

            bool run = Input.GetKey(KeyCode.LeftShift) || Input.GetKey(KeyCode.RightShift);
            bool jump = Input.GetKeyDown(KeyCode.Space);

            //States
            bool isGrounded = Physics.Raycast(groundDetector.position, Vector3.down, 0.01f, ground);
            bool isJumping = jump && isGrounded;
            bool isRunning = run && move_v > 0;// && isGrounded && !jump;

            //Jumping
            if (isJumping)
            {
                rig.AddForce(Vector3.up * jumpForce);
            }

            //Movement
            Vector3 direction = new Vector3(move_h, 0, move_v);
            direction.Normalize();

            float adjustedSpeed = speed;
            if (isRunning) adjustedSpeed *= runModifier;

            Vector3 targetVelocity = transform.TransformDirection(direction) * adjustedSpeed * Time.deltaTime;
            targetVelocity.y = rig.velocity.y;
            rig.velocity = targetVelocity;

            //animation
            if (direction.magnitude > 0f)
            {
                animator.SetFloat("MoveX", move_h);
                animator.SetFloat("MoveY", move_v);
                if (isRunning)
                {
                    animator.SetFloat("Speed", 2.1f);
                }
                else
                {
                    animator.SetFloat("Speed", 0f);
                }
            }
            else
            {
                animator.SetFloat("MoveX", 0f);
                animator.SetFloat("MoveY", 0f);
                animator.SetFloat("Speed", 0f);
            }
        }
        private void LateUpdate()
        {
            if (!photonView.IsMine) return;
            float mouseX = Input.GetAxis("Mouse X") * mouseSensitivity * Time.deltaTime;
            float mouseY = Input.GetAxis("Mouse Y") * mouseSensitivity * Time.deltaTime;
            xRotation -= mouseY;
            xRotation = Mathf.Clamp(xRotation, -50, 40);
            playerBody.Rotate(Vector3.up * mouseX);
            spine.rotation = Quaternion.Euler(spine.eulerAngles.x + xRotation, spine.eulerAngles.y, spine.eulerAngles.z);
            spine.localEulerAngles = new Vector3(xRotation, 0, 0);
            normalCam.transform.localRotation = Quaternion.Euler(xRotation, 0f, 0f);
        }

    }

}

Answer 2

エスパー回答ですが、Photonで共有しているゲームオブジェクトを削除する時にPhotonNetwork.Destroy()ではなく普通のDestroy()を使っているのが原因ではないかなと思います。

ご回答ありがとうございます。
後から分かった事として上記の'原因のプログラム'をオフにすることですべてのエラー、またはすり抜けるバグなどが直りました。ただ、このコードのどこが原因かがわかっておらず、このプログラムはプレイヤーを動かすのに必要なので、どこをどう変更すれば良いでしょうか?
