I installed ubunty 18.04.4 from a flash drive as a second system, next to windows10.
I can not log in to the system - it constantly redirects to the authorization window.

See if you've run out of disk space.

Answer 2

If you manage to get into the console, then try to do something from there: install another DE, change DM, or manually start the X server.
