Honestly, I don't really know. I have done nothing different from what I usually do. But I think the problem is on your end, if you look closer at the error, it is pointing at files on your computer. Maybe some corrupted files? Perhaps reinstalling the Itch.io app would solve it? If not I would advise asking for support from the Itch.io staff as I don't directly interact with their app when I upload files to their site.

Yeah looked into the error myself it's apparently a known issue https://itch.io/t/314040/cant-download-some-games-through-the-desktop-applicatio... I've followed the advice in this post so hopefully it'll be sorted out soon if not i'll bite the bullet and install winzip to download using my browser (personally I blame my overreliance on steam) cos I really wanna continue my romance with Eleanor thank you for your time!
