Overflow Exception

[EgilSandfeld]

Had a crash from one end-user of my app:
Any ideas how this was caused?

.NET Framework 4.8 app

Arithmetic operation resulted in an overflow,

   at System.IntPtr.op_Explicit(IntPtr value)
   at Gma.System.MouseKeyHook.KeyEventArgsExt.FromRawDataGlobal(CallbackData data)
   at Gma.System.MouseKeyHook.Implementation.GlobalKeyListener.GetDownUpEventArgs(CallbackData data)
   at Gma.System.MouseKeyHook.Implementation.KeyListener.Callback(CallbackData data)
   at Gma.System.MouseKeyHook.WinApi.HookHelper.HookProcedure(Int32 nCode, IntPtr wParam, IntPtr lParam, Callback callback)
   at Gma.System.MouseKeyHook.WinApi.HookHelper.<>c__DisplayClass7_0.<HookGlobal>b__0(Int32 code, IntPtr param, IntPtr lParam)

"targetSite": "Int32 op_Explicit(IntPtr)"
"type": "System.OverflowException"

The crash log above happened within 1 second of the app starting up, however I just received one now, with the similar stacktrace happened 34170 seconds into the app session..

Calling code to set up subscribers:

private void SubscribeKeyboard()
        {
            try
            {
                if (_appKeyboard == null)
                {
                    _appKeyboard = Hook.AppEvents();
                    _appKeyboard.KeyDown += AppKeyboardDown;
                }

                if (_keyboard == null)
                {
                    _keyboard = Hook.GlobalEvents();
                    _keyboard.KeyPress += KeyboardKeyPress;
                    _keyboard.KeyDown += (sender, args) => Core.Dispatcher.OnKeyboardDown?.Invoke(sender, args);
                    _keyboard.KeyUp += (sender, args) => Core.Dispatcher.OnKeyboardUp?.Invoke(sender, args);
                }
            }
            catch (Exception ex)
            {
                DB.AddBugInfo(ex);
            }
        }

I believe Hook.GlobalEvents(); call is the one facilitating the later crashes.

Can a missing System.Reactive.dll be the cause of this? So when the user presses a key, the missing dll causes the above stack?
