I suddenly began getting an version error with the .NET Assembly:
    Write-Error: Exception calling "Open" with "1" argument(s): "The version of C:\Program Files (x86)\WinSCP\winscp.exe (6.1.2.0) does not match version of this assembly C:\Program Files (x86)\WinSCP\netstandard2.0\WinSCPnet.dll (6.1.1.0)."    
I’m guessing it may be caused by a recent WinSCP software update.
I tried downloading & installing the (hopefully) newer version of the .NET Assembly from the WinSCP site, but I then I got a 
different error message:
    Write-Error: Exception calling "Open" with "1" argument(s): "Method not found: 'Void System.Threading.EventWaitHandle..ctor(Boolean, System.Threading.EventResetMode, System.String, Boolean ByRef, System.Security.AccessControl.EventWaitHandleSecurity)'."
    
Debug log is attached.
My PSVersionTable:
    PSEdition                      Core
GitCommitId                    7.3.7
OS                             Microsoft Windows 10.0.19045

What do I have to do to make this work?
