Strange error

I have a company/school account for Adobe CC. When signing in, I am redirected to our SSO page to sign in. 

I have tried the following - sign out of CC and sign in through Acrobat, signed in through CC and then sign in to Acrobat. Uninstalled and reinstalled Acrobat. 

The same error happens in all instances. 

When in Acrobat, after signing in, I see the following strange pop up appear, and if I close it, it will close the entire program.  So as of now, Acrobat is totally unusable
