I'm so sorry you're facing trouble, it seems like a series of unfortunate things piling up. The original error that started it all is one I'm familiar with, I dealt with it early in development and it's quite a surprise to see it pop back ^^ I think a lot of problems come from the fact that you're playing the game embedded in itch.io, it's an environment that I have very little control over so I have a hard time diagnosing bugs and understanding what's going on, it could be due to the interaction between itch and the game. I think if you download the game files it should work better, but maybe you'd rather play online, in which case I have a version hosted on my website: http://yo252yo.com/rd?winarg you can transfer save files between any version so don't worry about this. I'd be very surprised if your problems persist outside of the itch embed frame.
Sorry again
