    Hi, calling CallWindowProcW(wndProc, hWnd, message, wParam, lParam) with the following parameters in our game will cause UnityPlayer.dll to crash. Does anyone know the possible reason?

    It is a recently launched game, and Unity should be a relatively new version.

    Isn't it your game?
    Then make the devs post the issue and report the issue to them

    You are not supposed to call WM_QUIT in middle of the game loop, Unity doesn't expect that (and I can't even tell whether you're calling it from the right thread). Call Application.Quit() instead.

    Message 16 is WM_CLOSE. We captures all windows messages, deals with it (in this case, it doesnt do a lot) and retransmit if needed to the actual game using CallWindowProc. In this case, we got a WM_CLOSE from Windows and retransmit it to the game.

    Do you have a full callstack with "External Code" frames expanded?

    Re WM_QUIT/WM_CLOSE: my bad, I typed the wrong thing. However, the same thing applies to WM_CLOSE. That said, if Windows is sending this message, it shouldn't be crashing.
