It is working correctly on PS 5.1 and PS 7.2.1 and on older daily builds of PS 7.3. I was able to narrow the offending code to the following:\r\n```powershell\r\nGet-CimInstance -ClassName 'Win32_NetworkAdapterConfiguration' |\r\n\tWhere-Object -Property IPEnabled |\r\n\tForEach-Object {\r\n\t\t[IPAddress]::Parse(\r\n\t\t\t$_.IPSubnet[\r\n\t\t\t\t[Array]::IndexOf($_.IPAddress, $_.IPAddress[0])\r\n\t\t\t]\r\n\t\t)\r\n\t}\r\n```\r\n\r\nError:\r\n```powershell\r\nParserError: D:\\Users\\Bukem\\Documents\\PowerShell\\SCRIPTS\\Test.ps1:6\r\nLine |\r\n   6 |                  [Array]::IndexOf($_.IPAddress, $_.IPAddress[0])\r\n     |                        ~\r\n     | Missing ] at end of type token.\r\n\r\n```\r\n\r\nThe *fix* is to enclose the ` [Array]::IndexOf($_.IPAddress, $_.IPAddress[0])` in extra pair of parentheses. Like so:\r\n```powershell\r\nGet-CimInstance -ClassName 'Win32_NetworkAdapterConfiguration' |\r\n\tWhere-Object -Property IPEnabled |\r\n\tForEach-Object {\r\n\t\t[IPAddress]::Parse(\r\n\t\t\t$_.IPSubnet[\r\n\t\t\t\t([Array]::IndexOf($_.IPAddress, $_.IPAddress[0]))\r\n\t\t\t]\r\n\t\t)\r\n\t}\r\n```\r\nBut as I mentioned before the original code is working on PS 5.1, PS 7.2.1 and older daily builds of PS 7.3 so it has to be a recent change in the PS 7.3 code that is causing this.\r\n\r\n### Expected behavior\r\n\r\n```console\r\n. .\\Test.ps1\r\n\r\nAddressFamily      : InterNetwork\r\nScopeId            :\r\nIsIPv6Multicast    : False\r\nIsIPv6LinkLocal    : False\r\nIsIPv6SiteLocal    : False\r\nIsIPv6Teredo       :
