okay so I had a similar problem as you so I ran the game through WinRAR and that seemed to fix it, but I don't know why the game doesn't load through the Itch.io launcher.
Indeed, the game is an archive only, it was not set up in the itch launcher. I'll try to fix it up for the next update :)
My issue was apparently in my audio settings. I had my frequency set to 384khz, reducing it to 44khz allowed me to run the game.
