I have Windows 10 Pro, version 2004. I downloaded the standalone version as well, but it also crashed.
If you're willing to help test, I just uploaded a debug version on my itch page that will give you a console that should show the error when it crashes. It would be really helpful if you could grab a screenshot of any errors showing up in that console!
Go to my page and grab: fiends_isle[windows]_v0_6_6_DEBUG.zip
