It's not possible to call up a method for a term/expression that have NULL

[In139]

When I try to create a Windows 11 Enterprise ISO (German localisation) for Surface 8 Pro I get the following error message (only in German language):

Es ist nicht möglich, eine Methode für einen Ausdruck aufzurufen, der den NULL hat.
In C:\Users\_PATH_TO_\SurfaceDeploymentAccelerator\CreateSurfaceWindowsImage.ps1:2002 Zeichen:9
+         $global:WinPEVersion = (& $DISMFile /Get-WimInfo /WimFile:$Im ...
+         ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : InvalidOperation: (:) [], RuntimeException
    + FullyQualifiedErrorId : InvokeMethodOnNull

But not found such a line in the log file.
