    Resolution Note (fix version ):

    Won't fix in the tutorial.
    This is due to Unity version compatibility with tutorial. In latest version of the Hub, Tutorial will look for compatible version or suggest to install one.
    This current issue will be be consider as part of tutorial compatibility issue, and will be resolve with new tutorial UX.
