Windows 11 24H2 Start Menu and Taskbar Pinning Feature Malfunction

After upgrading the system to Windows 11 version 26100.4061 (24H2), the “Pin to Start” option has disappeared from the right-click menus of applications (including both built-in system apps and third-party software). Additionally, the “Pin to Taskbar” functionality is no longer working. Attempts to manually create shortcuts or move items to the “Start Menu” folder have proven ineffective. Seeking a solution to restore this functionality or a fix for this issue.
