Issue Description

When I run the following script under the PowerShell debugger within VScode, it hangs when launching exiftool.exe:

$exiftool = (Get-Command exiftool).Path
Write-Host ("'exiftool' is '{0}' (version {1}) {{MD5={2}}}" -f $exiftool, (Get-Item $exiftool).VersionInfo.ProductVersion, (Get-Filehash -Algorithm MD5 $exiftool).Hash)
$cmd = "{0} -DateTimeOriginal {1}" -f $exiftool, (Join-Path -Path $PSScriptRoot -ChildPath 'foobar.cr2')
Write-Host ("Invoking '{0}'" -f $cmd)
Invoke-Expression $cmd

Expected Behaviour

When running outside of the debugger (in a standalone PowerShell session, or in the VScode terminal), I get the expected results:

'exiftool' is 'c:\usr\wbin\exiftool.exe' (version 12.2.1.0) {MD5=4ECB5A8B4AA893F3ADFD48E8ACEBC669}
Invoking 'c:\usr\wbin\exiftool.exe -DateTimeOriginal S:\powershell\test\foobar.cr2'
Date/Time Original              : 2019:12:25 16:36:30

Actual Behaviour

When run via the debugger (F5 in VScode) the script hangs:

'exiftool' is 'c:\usr\wbin\exiftool.exe' (version 12.2.1.0) {MD5=4ECB5A8B4AA893F3ADFD48E8ACEBC669}
Invoking 'c:\usr\wbin\exiftool.exe -DateTimeOriginal S:\powershell\test\foobar.cr2'

Here’s the version of exiftool.exe on my system:

exiftool.zip
