UUuuuh wait. We might have an idea why the game crashes so often for you. Niki (dev) has the theory that both issues are coupled. Did you change your layout mid-game? Because this could cause the big issues.
As described in my previous comment: you could just leave your layout as is and play all swell in QWERTY, QWERTZ, AZERTY..., since the factory just asks to e.g. "hold A", "release B", "hold Y" - it does make no difference where the keys are located.
Hope this helps :) Have a great week!
