Virtualbox after 5.2.22 GA Install and Restart Windows Guest can’t Sign In

After installing  Virtualbox 5.2.22 Guest Additions and restart you can’t sign in. The Keyboard input is not recognised. Don’t try to restart from power button on login page as you end up going round in circles. Instead elect to Shutdown and then Start.

After this everything seems to be OK although I did not notice it took several minutes to shutdown the first time after successfully logging in. After this it shut down in the normal time frame.
