It looks like we had trouble getting the version of the flutter sdk; it's possible this is from an old flutter.

I've seen this as well but only very sporadically. From what I can tell from the one time I had it paused in a debugger, there is a bug in the vm implementation of identity hash map which is strange.

assumed fixed with the recent work to serialize service protocol resuests
