Modern Apps failed to start with error 5973
Today most of my modern Apps on Windows 8.1 stopped working, including Weather, Maps, Mail, Skype, Calendar, Contact, Stocks (and even Store App), i.e., when I click-open them, there is the short animation in which the App symbol is magnified to full screen, and then immediately afterwards I am sent back to the Metro interface. However, the apps do still appear in the taskbar.
