    Resolution Note:

    According to the UpgradeGuide in MRTK-2017.4.3.0 package is targeting Unity 2017.x products.

    # General Release Information
    This release is targeted for the Unity 2017.x products

    It seems like opening the project (that is using MRTK-2017.4.3.0 package) with Unity 2018.x may cause memory corruption due to the package incompatibility with Unity 2018.x products.

    Please rather downgrade the project to Unity version to 2017.x version or upgrade the MRTK packagage to version 2.0.0-+ that targets Unity 2018.x products.
