Hello Tim Ken.
Welcome to Microsoft Community.
Regarding to your information I assume that you have some issues when you using Windows 11 23h2.
Please click on the Desktop icon, collapse this folder, and then right-click in an empty space to deselect "Show all folders" and see if those folders
are still below.
Based on our testing, the main folder and the gallery can be deleted using the following steps:
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer]
"HubMode"=dword:00000001
[-HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Desktop\NameSpace_36354489\{f874310e-b6b7-47dc-bc84-b9e6b38f5903}]
