    Launching game on Windows 64-bit desktop does not work correctly for me on UE4 4.22.3


    I am very new to UE4 and I work in C++ mainly. I am intending to write a 2D game and am following a UE4 C++ Paper2D training video series.

    So far, I have a got a big pure white 2D background sprite in my scene and then a 2D spaceship sprite on top. The spaceship has a camera attached to it. Also the scene contains the default playerstart class. My sprites are blueprint classes generated off the C++ classes.
    The background sprite is an actor and the spaceship is a pawn. I also have default gamemode base class, which I haven't touched.

    In play mode, the game runs fine, but when I launch the game to my desktop, the window comes up, but at a random time (be it quickly or slightly later), the window shuts down by itself and UE4 gives a message saying "Launch canceled!" and the output log shows no error or indication as to why the game shutdown.

    The only deploy warning I can see in yellow is:

    LogPlayLevel: Warning: WARNING: Win64 does not implement Deploy...

    although this is shown sometime before the game actually is built and run and I don't think this affects the actual deployment?

    I am running Windows 10 and my PC is very basic with a AMD A9 CPU and integrated AMD Radeon R5 graphics. Basically, the PC is not very fast, to say the least, but I carry on! I am running Visual Studio 2019 Community Edition.

    My question is, is it a problem with UE4 or does my simple C++ code have some sort of runtime error?

    Thanks in advance,


    Check the C++ code with UE_LOG .



      Thanks wbreganh, I carried on with my game regardless and I normally run it in standalone or packaged.

      Now for some reason it launches fine now! :-)
