No idea what I'm looking at, gonna guess the itch.io app that is known to have lots of issues?
I'd recommend simply download and play as instructed above instead.
Yeah, that's the itch.io app. It's useful for games that update often, as it only downloads the new files and assets instead of the entire game each time. The only thing it's not great at (for me at least) is games that are hosted on unsupported sites. I don't know the entire list of supported sites, but I can tell you it's not a large selection.
