If I recall correctly, I opened print menu(cmd+p), closed it using esc, toggled full screen(cmd+ctrl+f), untoggled it (cmd+ctrl+f) and gave cmd+p again. Orion crashed on this.
But I can't seem to reproduce it again
Will post a crash report once Orion prompts (Haven't received system crash report yet either so waiting on it)
EDIT: Have sent the crash report
