    Hi,this is the first post :)

    Assertion failed on expression:'IsMatrixValid(matrix)'
    holographic tracking state lost. New State:1

    Connected successfully but when I played the scene, all crashed.
    The console showed above.

    Unity: 5.6.0f3
    I used the Wireless LAN Card to connect the computer and Hololens.

    BTW, there is a Javascript on the scene to make the cube rotates. Show as below.
    #pragma strict
    function Start (){
    function Update(){

    I'm not sure the problem is about Microsoft or Unity.
    Thanks for any suggestion.

    That assert about the invalid matrix is coming from Unity, but it's in generic code I don't usually touch, so it's hard to guess what might be the problem.

    Would you mind filing a bug with your repro project so we can take a look? Please remember to prefix the title with "[HoloLens]" so it gets through the system to us as quickly as possible. Thanks!
