We found a fix finally. Hopefully it'll work for you:
On your Windows desktop, add new administrator/user profile.
You don't need to add an account/email to associate with that profile, just add as a local user.
Once new user profile added, login to Windows under that profile and you'll go through the normal Windows setup process. Once that's complete, start QB, login and try the Incorporate Accountants Changes again. If that worked, you can log back into your original windows profile and double check the accountant changes were incorporated.
Hope that helps!
