It doesn't really freeze. It just closes :-(
I just had it occur during an auto save while I was trying to close a script window, so I'm not sure if it's even linked to corona.
I'll try to see if there is a minidump but I don't think so because it doesn't seem like an error is registered, it just seems like it closes the program without saving or something.
I'm going on vacation right now, so it might be a while (maybe next month).
