Powershell7 WinSCP New-WinSCPSession Exception

I have an existing Powershell script which works without issue in PowerShell 5.1. After installing PowerShell 7, the script no longer works and it fails when trying to establish a WinSCP session.

First, session options are created via New-WinSCPSessionOption, and those options are stored to $sessionOption without issue.

$sessionOption = New-WinSCPSessionOption -HostName $hostName -Credential $credentials -Protocol Ftp

When the session setup runs, an exception is thrown in Powershell 7:

$session = New-WinSCPSession -SessionOption $sessionOption

The following exception is thrown:

Line |
 |      $session = New-WinSCPSession -SessionOption $sessionOption
 |                 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 | 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)'."
