Shortcuts Pinned to Taskbar Keep Disappearing

Occasionally, when attempting to pin a new app to the taskbar, the existing pinned shortcuts vanish abruptly, prompting a need to re-pin them. This issue arose multiple times when trying to add the PowerShell 7 terminal to the taskbar. Furthermore, whenever I re-pin the shortcuts, numerical increments are added to the app labels, similar to file copying scenarios where duplicates are labeled with numbers, for instance: Discord (4), Brave (4), PowerShell 7 (x64) (3). I am curious if the pinned shortcuts are duplicated in a designated folder location, resulting in the appended numbering. Is there a way for me to manage, relocate, or create backups of these pinned shortcuts?
