Windows 10: Windows Menu and Windows settings are not working

I can't open windows settings in any way, the windows key doesn't open any menu not even if I click on the icon, the search doesn't open any menu, I've already tried to enter through the internet settings, through the windows defender settings, I can't enter through the start screen customization, or in any way, I feel like this happened after an update, I don't know if this could be the cause or there's something else. I appreciate any help, thank you very much in advance.

Feature suggestion: Add right-click menu

Suggestion: Please add a Windows 7 Jump-List and/or right-click menu to the GPU-Z icon in the Windows taskbar. Possible menus in it would be "Exit" and "About GPU-Z...".
Maybe also "Switch to tab 1/Switch to tab 2/Switch to videocard 1/Switch to videocard 2" too.
Examples of programs that have such menus are ICQ, Skype, AIM.

NOTE: It seems for a right-click menu, Windows 7 is not needed - it works on WinXP and Vista too.
But even a Windows 7 Jump-list may be good enough.
What do you think?

 

Feature suggestions - move to proper menus, add Options window

Suggestions:
1) Remove main menus from top left menu (system menu) and move them to a standard Windows menu, at the top.
Leave the 6 system menu items (Restore --- Close) in system menu, move all the rest to that standard main menu. The main menu can be auto-hidable - pressing Alt key to invoke it or hide it, similar to the way IE11 menus and many Windows 10 built-in apps' menus work.

2) And/or, add an Options menu or button, which would invoke a separate screen with GPU-Z Options, similar to how most Windows apps work.
Most Windows apps have a separate Options screen, which GPU-Z lacks - one should be added.

Thanks in advance for listening!
