This is a very bizarre bug, but I think I've finally killed it now. My last fix was only a 'half fix', and now it should be 'FULL FIXED'.
I've had it running on 3 or 4 different computers just fine, but looking at the code where you crash this should not be possible... But I think I have fixed it for you now.
If you have the itch.io app it will be a much smaller update for your game, otherwise I'll have to ask you to download and install the game again.
You can just download the game from the store page again for the latest version. Thanks so much for your patience and I really REALLY hope it works for you this time. And do let me know what you think about the game if you get a chance to play it!
