It's running ok for me, through the app, on windows 10 pro v1903. Does the message looks like it's from itch or from windows? Do other (old) gamemaker games work for you, e.g. original spelunky? And what happens if you download the zip file, outside the app, unpack it and run it?
i do run it from windows and yes i can run older games but the message does look like it came from a windows message. then again thats all it shows.
