Error is
Import-Module: Could not load file or assembly 'ICSharpCode.SharpZipLib, Version=1.4.2.13, Culture=neutral, PublicKeyToken=1b03e6acf1164f73'. The located assembly's manifest definition does not match the assembly reference. (0x80131040)
when loading bin\netstandard2.0\PSCompression.dll
Can repro with
install-psresource vcf.powercli
Import-Module Vmware.VimAutomation.Core
Import-Module PSCompression -Verbose
I guess ALC is out the picture if you want to support 5.1.
