Don't worry. I have some problems on my own which are preventing me from responding soon.
The itch.io version should also have an error log.
Windows 10 "conveniently" hides the AppData folder from being seen regularly; almost thought it wasn't real XD. Anyway, I replicated the error where the game becomes unresponsive at the character select screen. Unfortunately I can't send files through here, but the file was mainly repeating the following:
(Filename: Line: -1)
IndexOutOfRangeException: Array index is out of range.

Then ended with this.
