Windows 10 Sign In button doing nothing - Unable to sign in

[Winprice]

For all of the PCs I have at home, one is not letting me sign in.  I enter my email and password and click on the Sign In button, and it does nothing.

Has anyone seen and been able to resolve this?  I have approved my PC, but it has been installed on this PC literally for YEARs.

The log file shows this error:

2018/09/04 11:02:16.291 18256  4844 G3!!  AccountLoginStateMachine::OnLoginStarted: m_ssoLoginManager missing

Thanks in advance!
