Start by reproducing the crash on Windows 11 with Python 3.12.10 in the frozen app, using the reported log at C:\Users\David.local\state\tuney\tuney.txt. Investigate the _rtmidi MidiOutWinMM.openPort failure during startup. Done means the application no longer crashes during startup in this environment.
