Module fails to import/connect on PowerShell 7.6.x — Add-Type can't resolve System.Private.ServiceModel

[Jakez84]

Module version: Autotask 2.0.3 PowerShell versions tested: 7.2.24 (works), 7.6.3 and 7.6.4 (both broken) OS: Windows

Import-Module error:

Add-Type: Cannot find path 'C:\Users...\System.Private.ServiceModel.dll' because it does not exist.

Connect-AtwsWebAPI error:

New-Object: ...\Autotask\2.0.3\Private\Connect-AtwsWebServices.ps1:93

| Cannot find type [Autotask.ATWSSoapClient]: verify that the assembly containing this type is loaded.

Commenting out 'System.Private.ServiceModel' in Autotask.psm1 seems to resolve the issue
