Explorer broken, no icons: desktop, explorer, context menu, taskbar default icon for exe

Good day,

I hope you can help me to save my W11, because the system is fresh, customized and all programs are installed.
In the attachment you can see that all icons have disappeared.
It was probably me, but not sure what went wrong. I did the following in the registry:

-Remove “Open with Visual Studio” from Folder Context Menu, for this the folder AnyCode must be deleted

KEY_CLASSES_ROOT\Directory\Background\shell\AnyCode

-Remove AMD Context menu, a new key must be created for this purpose

-Activate window by mouse over, default 500ms, I have reduced it to 100

I can't think of any other settings. I also did not do anything like “Remove link arrow”.

I have undone the last two changes. One program, Windhawk, changes the design of the taskbar, but this program ran for a week without any problems. I turned it off without any improvement.

Also the task manager is not appearing (ctrl+alt del, nor taskbar right click).

W11 Enterprise, 10.0.26100

Many thanks,
mrspec

EDIT: Explorer restart no help, cmd -> taskkill /f /im explorer.exe && start explorer.exe

You can use the attached batch script to delete icons cache and reboot your system to see the problem fixed.

If the batch script doesn't resolve the problem, you can try in-place upgrade repair Windows 11.

You can also perform in-place upgrade of Windows 11. In-place upgrade is to use to replace the current operating system files on your computer. Unlike a clean installation of Windows, you can start a Windows in-place upgrade when your OS is still running. And an in-place upgrade can keep your files, settings, & apps during the upgrade process. You can perform a Windows 11 in-place upgrade is to use the Windows 11 Media Creation Tool. Make sure to select Upgrade this PC now and click Next. Follow the on-screen guide to perform a Windows 11 in-place upgrade.

Inplace Upgrade is done, didn't helped.
Also I have other problems, the mentioned task manager not appearing, I can't create a restore point, I can't create a backup (control panel -> backup and restore (w7).
I gonna run your batch script.
EDIT: Didn't helped.

Execute Sfc /scannow command.
