Ran "wine reg add "HKCU\Software\Wine\X11 Driver" /v UseEGL /d N /f". iTunes crashes afterwards.
This might still be related, as we try to enumerate EGL devices unconditionally, and the patch above should also hopefully help. Fwiw you can also undo that command and reset the option to its default (which is to use EGL for now) with:
wine reg delete "HKCU\Software\Wine\X11 Driver" /v UseEGL /f
