Photon 2 InvalidCastException: Specified cast is not valid. RigidBodyView

Wherever i try to get in the scene with the client appears this error:

InvalidCastException: Specified cast is not valid.

And this is the code that doesn't works:

public void OnPhotonSerializeView(PhotonStream stream, PhotonMessageInfo info) 
    { 
         if (stream.IsWriting) 
         { 
             stream.SendNext(this.m_Body.position); 
             stream.SendNext(this.m_Body.rotation);

             if (this.m_SynchronizeVelocity)
             {
                 stream.SendNext(this.m_Body.velocity);
             }
             if (this.m_SynchronizeAngularVelocity)
             {
                 stream.SendNext(this.m_Body.angularVelocity);
             }
         }
         else if (stream.IsReading)
         {
             this.m_NetworkRotation = (Quaternion)stream.ReceiveNext();
             this.m_NetworkPosition = (Vector3)stream.ReceiveNext();
             if (this.m_TeleportEnabled)
             {
                 if (Vector3.Distance(this.m_Body.position, this.m_NetworkPosition) > this.m_TeleportIfDistanceGreaterThan)
                 {
                     this.m_Body.position = this.m_NetworkPosition;
                 }
             }
             
             if (this.m_SynchronizeVelocity || this.m_SynchronizeAngularVelocity)
             {
                 float lag = Mathf.Abs((float)(PhotonNetwork.Time - info.SentServerTime));
                 if (this.m_SynchronizeVelocity)
                 {
                     this.m_Body.velocity = (Vector3)stream.ReceiveNext();
                     this.m_NetworkPosition += this.m_Body.velocity * lag;
                     this.m_Distance = Vector3.Distance(this.m_Body.position, this.m_NetworkPosition);
                 }
                 if (this.m_SynchronizeAngularVelocity)
                 {
                     this.m_Body.angularVelocity = (Vector3)stream.ReceiveNext();
                     this.m_NetworkRotation = Quaternion.Euler(this.m_Body.angularVelocity * lag) * this.m_NetworkRotation;
                     this.m_Angle = Quaternion.Angle(this.m_Body.rotation, this.m_NetworkRotation);
                 }
             }
         }
     }

Hi @agustin9594,

Thank you for choosing Photon and sorry for the delay!

What PUN 2 version is this?
When you try the Asteroids demo scene provided in the package, can you reproduce?
Did you modify PhotonRigidbodyView or any other PUN 2 code?
