That folder is no longer a "real" directory; it's a junction point:

C:\>dir /al "%allusersprofile%"

01/09/2020  14:45    <JUNCTION>     Application Data [C:\ProgramData]
01/09/2020  14:45    <JUNCTION>     Desktop [C:\Users\Public\Desktop]
01/09/2020  14:45    <JUNCTION>     Documents [C:\Users\Public\Documents]
01/09/2020  14:45    <JUNCTION>     Start Menu 
[C:\ProgramData\Microsoft\Windows\Start Menu]
01/09/2020  14:45    <JUNCTION>     Templates 
[C:\ProgramData\Microsoft\Windows\Templates]

which means, amongst other things, that whilst you can copy files into 
it you cannot enumerate the contents or delete objects. Unhelpfully, it 
seems that del returns zero when it can't find a file so wpkg will 
believe the command has completed successfully...

C:\>dir "%allusersprofile%\desktop"

Directory of C:\ProgramData\desktop

File Not Found

C:\>del "%allusersprofile%\desktop\list.txt"
Could Not Find C:\ProgramData\desktop\list.txt

C:\>echo %errorlevel%
0

If you continue using "%public%\desktop" you will get better results.
