If it's possible, I would ask the tool developer to provide you with a command line or XPC version and try accessing these state transitions in a more UI-thread-friendly manner.
Have you stopped your debugger when the freeze happens to see what your main thread stack frame looks like? It might give you a clue what you can do, if anything. Use that, Instruments, and the Activity Monitor app if ran on a non-developer's machine.
