Hy 👋, thanks for reporting 😃, this may likely be the same as this issue here:

As a workaround, you can try the other version (portable)
Looks like it, and I can confirm using the boring regular version does in fact work ;)
Related feature request, I guess: when you install via the itch.io desktop app, you end up with a folder containing a zip file, and not something you can just run. It’d be cool if you could make that work! Some apps that I’ve seen work this way are Ditherdragon and Crocotile3D (in addition to a bunch of games)
