App crashes at end of game if one side checkmates while engine evaluating

[KitchenTable99]

When stockfish is evaluating a position that ends in checkmate, the app displays a pop-up saying that one player or another has won. If you do not stop the evaluation and walk through the moves to see the checkmate, the app crashes. I have tested this with five different openings and was able to recreate the bug each time. The only difference is the time that it took for the app to crash which varies from instantaneous to about ten seconds.

Let me know if there's anything else you need!
