That’s unfortunately not very helpful. Could you please give us a bit more info here like: with which song did that happen, do you had other problems with the song before and what have you done before it crashed (even if it seemes not be directly related to the crash). Does the song use a bunch of plugins which you maybe just started using? Could you share the song with us?
Is that maybe related to the IL Mini Host crash you previously reported?
According to the crashlog it tried to clean up/delete an objc object of a class which no longer is registered. This may happen when some object of an already unloaded plugin is still dangling around. But it also may happen when heap memory got corrupted - either by Renoise or some plugin. Hard to say, really.
