There is no error when the game crashes. I looked at the game files, but it doesn't seem to save error information.

This is why he mentioned the Debug mod(https://itch.io/t/1137280/debugmod-v10d), as it changes how the game reacts to errors and enables the display of error messages. It will not fix your errors but the error messages should pinpoint the locations in the scripts that the errors occurred.
