Why is start not working in windows 10?

Question

Microsoft

The start icon suddenly stopped working, I press it and nothing happens, Pressing the button on the keyboard does not help either. Well, besides this, the notification center, network management, and volume control do not open. If you click on the start button with the right button, a menu opens, which should open. but it still won't open.

Answer 1

The problem is in the update that arrived today. rolled back and everything is ok

Answer 2

There is a new version out now and it hasn't been fixed yet. which update should be removed? (updated since 7)

Answer 3

Colleagues, I'm sorry to raise an old question, on the computer of my parents Windows 10 1909, I've tried everything already, I can't figure out how to fix the button. already restarted processes, looked for viruses, there were no updates for half a year, they were banned for a long time, utilities and new programs were not installed, antivirus was built into the system, there were no damaged components in the system.
