    Hi...
    I'm using a library (NumpyDotNet) to do some math calculations.
    When I run the app on Hololens 2 (or emulator), a particular operation throw an exception.
    If I run the same project, same code with the same input values on Unity, with debugger attached, everything works fine.
    Could you help me understand what is going on?!? Are there known limitations of this kind?

    The only thing I can think of is that NumpyDotNet is doing something that ARM64 doesn't like. Without knowing more (at least a exception call stack?) not much more I can tell you.

    And I've never used NumpyDotNet so I can't help you with that directly.

    There is the chance that it's an il2cpp issue but that's beyond my ken. Not sure an appropriate other forum to post in right now.

    I just inspected the library and I saw some dynamic keyword...
    I think this might be the problem with IL2CPP.
    Thanks!
