Sunfish freezes after a while.

hi. so, I'm running sunfish on Windows, with Python 3.11. to run it, I've created a .bat file, with the following contents:
python ./sunfish.py
and then I hook it up to Pychess. so, there are a lot of positions where it just freezes, and when I use the ask to move feature it dies. the engine generally prefers the Sicilian defense as black, and I generally play the smith-morra gambit against it. after e4, c5, d4, xd4, Qxd4, Nc6, Qd1, it just freezes, and dies. there are many other positions like this, and I don't think I have managed to complete a single game with it. I don't know if it's trying to make an illegal move or anything.
also, the NNUE version doesn't freeze it straight up dies.

That's not good. Can you give an example, without using UI, where it crashes?
