EventLog access is not supported on this platform

[mwithheld]

When I run the sample code as admin:

#test-posheventlog.ps1
Import-Module PoShLog
Import-Module PoShLog.Sinks.EventLog
New-Logger |
    Add-SinkEventLog -Source 'PoshLogs' |
    Start-Logger
Write-InformationLog 'My message in windows event log'
Close-Logger

I get this error:

PS C:\Scripts\> .\test-posheventlog.ps1
Exception calling "EventLog" with "9" argument(s): "EventLog access is not supported on this platform."
At C:\Program Files\WindowsPowerShell\Modules\PoShLog.Sinks.EventLog\1.0.0\functions\sinks\Add-SinkEventLog.ps1:56 char:3
+         $LoggerConfig = [Serilog.LoggerConfigurationEventLogExtension ...
+         ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : NotSpecified: (:) [], MethodInvocationException
    + FullyQualifiedErrorId : PlatformNotSupportedException

I have registered the event source as admin, and tested this works:

New-EventLog -LogName Application -Source PoshLogs
Write-EventLog -LogName "Application" -Source "PoshLogs"

I tried a fresh re-install of .NET 6.0.14 SDK and full machine restart.
Install was fresh today:

Install-Module -Name PoShLog
Install-Module PoShLog.Sinks.EventLog

Windows Server 2019
Powershell 7.3.3

Get-ChildItem 'HKLM:\SOFTWARE\Microsoft\NET Framework Setup\NDP' -Recurse | Get-ItemProperty -Name version -EA 0 | Where { $_.PSChildName -Match '^(?!S)\p{L}'} | Select PSChildName, version

PSChildName Version  
----------- -------  
Client      4.7.03190
Full        4.7.03190
Client      4.0.0.0  

Any suggestions would be appreciated.

Figured it out- it fails under PowerShell ISE but works when run in pwsh version 7

The issue is actually a bug in serilog and .NET Foundation 4.8 affecting PS 5.1 and ISE: serilog/serilog-sinks-eventlog#49
