Adobe Acrobat Standard DC infinite loading when signing in

[wilz_4589765]

I'm having issues signing in to the Adobe PDF reader app. See screenshots below. It just says loading indefinitely in the sign-in app (which is a separate application). And whenever I open up a PDF this separate app auto-opens and wants me to sign in. But that's not working. I don't have a Creative Cloud app on my computer - I only use the Adobe Acrobat Standard DC app.

I have the same exact issue!
