   I confirm this issue, detected in the first place with a script that invokes ROBOCOPY.EXE (which is part of Windows).

   Here's my repro script, and its output (args.exe is my homegrown equivalent to EchoArgs, that I wrote a zillion years ago):

   ----------------------------8<---------------------------------------------
   $xmldata = @'
   <Objs Version="1.1.0.1" xmlns="http://schemas.microsoft.com/powershell/2004/04">
   <S>/s</S>
   <S>/xx</S>
   <S>/xo</S>
   <S>/np</S>
   <S>\\bar\c$\a b\</S>
   <S>E:\foo</S>
   </Objs>
   '@

   $xmlfile = Join-Path -Path $env:TEMP -ChildPath 'VSCodeArgsProblem_data.xml'
   $xmldata | Out-File $xmlfile
   $robocopy_args = Import-Clixml -LiteralPath $xmlfile
   Remove-Item -LiteralPath $xmlfile
   & args $robocopy_args

   ----------------------------8<---------------------------------------------

   -----------------------------------------
   Universal command line arguments debugger
   argv[0] = 's:\bin\windows\x86\Args.exe'
   -----------------------------------------
   argv[0]='s:\bin\windows\x86\Args.exe'
   strlen(argv[0]) = 27
   argv[1]='/s'
   strlen(argv[1]) = 2
   argv[2]='/xx'
   strlen(argv[2]) = 3
   argv[3]='/xo'
   strlen(argv[3]) = 3
   argv[4]='/np'
   strlen(argv[4]) = 3
   argv[5]='\\bar\c$\a b" E:\foo'
   strlen(argv[5]) = 20

   sum(strlen(argv[i])) = 58

   Current working directory: 'C:\Users\steph'

   GetCommandLine() = '"s:\bin\windows\x86\Args.exe" /s /xx /xo /np "\\bar\c$\a b\" E:\foo'

   strlen(GetCommandLine()) = 67
