I uninstalled the itch app to reinstall it because it was being unreasonably slow.

My Itch installer keeps giving me this message: Get "https://broth.itch.zone/itch/darwin-amd64/26.1.9/signature/default?

I tried putting the url into a browser, but it just downloaded a weird document file that is named 3871300-signature-default

I need help getting my installer past this step so I can reinstall itch.
