Missing Windows 10 Action Center. How to get it back?

Question

Windows

Problem:
The Notification Center is missing and not working. Swipe from the right edge also does not work (touch screen).
Taskbar:
Settings "Turn system icons on and off":

Possible reasons:
This virus (Kaspersky let me down, installed Panda Security so that this would not happen again).
Or, more likely, a custom installation of the Meridian VK application ( download ZIP & start "Add-AppDevPackage.ps1" via PowerShell).

Answer 1

Drop the contents of powershell. In general, jokes are bad with him. There you can break everything so that without a complete reinstallation you can’t return the broken one.
