Start by reproducing winget configure --file blah.yaml as a non-admin user with the shown Microsoft.WinGet.DSC/WinGetPackage resource, then trace how the configure command selects the installer working directory. Use the Cygwin log as the failure signal; done means package downloads no longer target C:\Windows\system32 and the installation succeeds.
