Subsequent reports of this issue have clarified that the crash is reproducible by entering the first level (after the tutorial). The crash occurs as soon as the start timer hits 0. If the crash does not happen on its own, and you're not able to enter the first level, it has been confirmed that spam-clicking a Round One level will eventually get you into it so you can reproduce the crash.

There is potentially, though only speculatively, relevant conversation surrounding #993 and #3839
