NETwork Manaager hangs doing IP Scan.

Reproduce the hang from the reported Windows 11 Pro PowerShell steps, then start at the IP Scanner entry point and compare behavior before and after the winget upgrade. Done means the IP Scanner completes normally instead of leaving the spinner running indefinitely.
