• Refer to Differences between Windows PowerShell 5.1 and PowerShell.

Steps to reproduce

Run this script in PowerShell 7.2.1: https://superuser.com/a/1293303/298707

[CmdletBinding()] Param (
    [Parameter(Mandatory=$true)][ValidateSet('Off', 'On')][string]$BluetoothStatus
)
If ((Get-Service bthserv).Status -eq 'Stopped') { Start-Service bthserv }
Add-Type -AssemblyName System.Runtime.WindowsRuntime
$asTaskGeneric = ([System.WindowsRuntimeSystemExtensions].GetMethods() | ? { $_.Name -eq 'AsTask' -and $_.GetParameters().Count -eq 1 -and $_.GetParameters()[0].ParameterType.Name -eq 'IAsyncOperation`1' })[0]
Function Await($WinRtTask, $ResultType) {
    $asTask = $asTaskGeneric.MakeGenericMethod($ResultType)
    $netTask = $asTask.Invoke($null, @($WinRtTask))
    $netTask.Wait(-1) | Out-Null
    $netTask.Result
}
[Windows.Devices.Radios.Radio,Windows.System.Devices,ContentType=WindowsRuntime] | Out-Null
[Windows.Devices.Radios.RadioAccessStatus,Windows.System.Devices,ContentType=WindowsRuntime] | Out-Null
Await ([Windows.Devices.Radios.Radio]::RequestAccessAsync()) ([Windows.Devices.Radios.RadioAccessStatus]) | Out-Null
$radios = Await ([Windows.Devices.Radios.Radio]::GetRadiosAsync()) ([System.Collections.Generic.IReadOnlyList[Windows.Devices.Radios.Radio]])
$bluetooth = $radios | ? { $_.Kind -eq 'Bluetooth' }
[Windows.Devices.Radios.RadioState,Windows.System.Devices,ContentType=WindowsRuntime] | Out-Null
Await ($bluetooth.SetStateAsync($BluetoothStatus)) ([Windows.Devices.Radios.RadioAccessStatus]) | Out-Null

With either option .\bluetooth.ps1 -BluetoothStatus On or .\bluetooth.ps1 -BluetoothStatus Off.

Expected behavior

Run like in older PowerShell versions.

Actual behavior

Does not work.
