How do I fix my Microsoft account from signing into my computer?

On a Windows 10-based computer, the following error message appears on the screen after logging on to Windows: "We can't sign into your account" and all the user files and settings are missing. The problem may occur, because Windows, if the user's profile is corrupted for any reason (e.g. Windows Updates, Malware attack, damaged RAM or HDD) creates a new temporary profile and sign-in the user to it.
