Hi!

Is this a business account you are logging in with?
If so reach out to your administrator and ask if they are running ADFS and if any changes were done recently.
Although several other users should have this problem if this is the case

I have a similar case. It don't login in from my laptop (Windows 8). I have tried from others with Windows10 and it works. I have tried to uninstall and install again but the error remains. Any clues?
