My understanding is that MacRuby relied on Apple's ill-fated attempts to migrate from reference counting to regular garbage collection. I would be surprised if GC still worked on modern arm64 macOS. RubyMotion later adopted ARC but then it's not really Ruby anymore.
Gees, I forgot about their move to Arm. Almost certainly wouldn't work out of the box any more.
