Suggested solution to the issue

I have investigated this issue and discovered that Start-Process gives a security warning when a UNC path is used. This can be resolved by adding the used servername to the IE Local Intranet Zone: https://www.reddit.com/r/PowerShell/comments/7d49z3/start_script_from_uncpath_without_security_warning/ https://technochat.in/2008/12/disable-unc-path-security-warning-from-group-policy/

This can be resolved via PowerShell by executing:

$null = New-Item -Path "HKCU:\Software\Microsoft\Windows\CurrentVersion\Internet Settings\ZoneMap\Domains\$serverName"
Set-ItemProperty -Path "HKCU:\Software\Microsoft\Windows\CurrentVersion\Internet Settings\ZoneMap\Domains\$serverName" -Name file -Value 1 -Type DWord
$null = New-Item -Path "HKCU:\Software\Microsoft\Windows\CurrentVersion\Internet Settings\ZoneMap\EscDomains\$serverName"
Set-ItemProperty -Path "HKCU:\Software\Microsoft\Windows\CurrentVersion\Internet Settings\ZoneMap\EscDomains\$serverName" -Name file -Value 1 -Type DWord

The DSC configuration that is used to reproduce the issue (as detailed as possible)
