    Launch failed! Unknown Error

    ( I followed all steps: https://docs.unrealengine.com/latest...ettingStarted/ ! )

    This error comes up when I try to launch my Android project on my Handy:

    HTML Code:
    LogPlayLevel: ERROR: D:/DEVELOPER/Unreal Engine 4/NVPACK/android-ndk-r12b/ndk-build.cmd failed with args APP_ABI="armeabi-v7a " NDK_DEBUG=1
    LogPlayLevel:        (see C:\Users\C-PC\AppData\Roaming\Unreal Engine\AutomationTool\Logs\D+DEVELOPER+Unreal+Engine+4+UE_4.18\UAT_Log.txt for full exception trace)
    LogPlayLevel: AutomationTool exiting with ExitCode=1 (Error_Unknown)
    LogPlayLevel: Completed Launch On Stage: Deploy Task, Time: 2.505175
    LogPlayLevel: BUILD FAILED
    PackagingResults: Error: Launch failed! Unknown Error

      i had the same problem. i fix this with disabling the substance plugin. i think something crashing the assets while substance plugin is enabled.
