-BlockExecution hangs install (V4.1.0 )

The Toolkit General Discussion

I want to block users launching certain .exe's with some deployments as these interfere with deployments.

I am aware there was a bug in previous versions of v4 so I omitted the param in previous scripts however, v4.1.0, i tested the param again using "winword" as an example:

AppProcessesToClose = @( @{ Name = 'winword'; Description = 'microsoft word'})

$saiwParams = @{
        AllowDefer = $true
        DeferTimes = 3
        CheckDiskSpace = $true
        PersistPrompt = $true
    }
    if ($adtSession.AppProcessesToClose.Count -gt 0)
    {
        $saiwParams.Add('CloseProcesses', $adtSession.AppProcessesToClose)
    }
    Show-ADTInstallationWelcome @saiwParams `
    -Title $adtSession.InstallTitle -subtitle "Update" -NoMinimizeWindows -BlockExecution

the log is below:

But then nothing happens.... No errors, nothing.
