Eugh, that's a nasty one. Thank you for letting me know! Just checking I've read the error log correctly - this happens when you try to launch the game, correct?
It looks like the script that handles the game's audio settings is having issues. Normally it creates a file in your computer's AppData or ProgramData folder to store these settings, so whenever you make a change or load a save the volume levels remain consistent. Buuuut it looks like it crashes when it tries to do this, meaning something on your computer is blocking it.
It might be a clash with your computer's security settings, firewall, or operating system. (What version of Windows are you playing this on?)
I might be able to patch in a quick fix when I get home from work, but the volume might not work as intended. It may be easier to play the HTML5 version in the meantime.
