That's very interesting. It basically means it's not the game itself that crashed, but the low-level platform code. I don't think the file copy had anything to do with this, but is it possible that your controller disconnected just before the crash occurred? Looking around, it may be a possible explanation.
I had a couple more "almost" crashes where the game froze for quite some time to the point I was about to kill it in Task Manager when it suddenly came back. I'm on a Windows 11 machine. I decided to try something and set the Windows compatibility mode to Windows 8 and also disabled "fullscreen optimizations" and I haven't had any problems since, nor in any of your other Metroidvania games as I'm playing the last one now. Very enjoyable games! Thanks for making these gems!
