You may try to capture a crash dump by following these instructions.
I noticed that you are both sending and receiving MIDI from your Arduino as well as sending keystrokes to your operating system. Does the Arduino echo back the MIDI messages sent? Maybe there is a MIDI loop somewhere?
Is the source of you saxophone MIDI your Arduino WiFi and Bome MIDI Translator Pro connected to SWAM via Bome MIDI Translator 1?
I assume the keystrokes are for you game. If you disable your preset (so that only MIDI thru paths are in play), does it still crash?
