Recently I've had several people having a similar issue (just most of them have reported it in the Discord rather than here). I think there might have been some sort of Windows security change which restricts programs that create or modify files in certain directories. You can try running from a different directory, or try running the program from an Admin command prompt, to see if that resolves the problem - let me know if you need any help!
In general, there's a log file which is supposed to record crash info among other things, but I've seen that sometimes the log file itself is unable to be created due to permissions, so I'm suspecting that might once again be the issue.
