There is no error message printed during runtime.
I also added a feedback item with the same NSInvalidArgumentException, caused by a different app listed as: FB13872901.
It also might be the same problem as FB13872931.
Great to hear that it is being worked on! Do we get a notification when this has been fixed? As of beta 3 there is still no improvement. However thanks for picking this up!
