Error: Object reference not set to an instance of an object

[MomoOne]

Hello,

When I want to import the module with the command
Import-Module -Name CMLimitingCollection -Verbose
I have this following error:

VERBOSE: Loading module from path 'C:\Program
Files\WindowsPowerShell\Modules\CMLimitingCollection\1.0\CMLimitingCollection.psd1'.
VERBOSE: Loading 'FormatsToProcess' from path 'C:\Program
Files\WindowsPowerShell\Modules\CMLimitingCollection\1.0\CMLimitingCollection.Format.ps1xml'.

Import-Module : Object reference not set to an instance of an object.
At line:1 char:1

• Import-Module -Name CMLimitingCollection -Verbose

•   + CategoryInfo          : InvalidOperation: (:) [Import-Module], NullReferenceException
    + FullyQualifiedErrorId : FormatXmlUpdateException,Microsoft.PowerShell.Commands.ImportModuleCommand
  
  

The command Get-Module -ListAvailable gives me that:

Directory: C:\Program Files\WindowsPowerShell\Modules

ModuleType Version Name ExportedCommands

---

Script 1.0 CMLimitingCollection {Set-LimitingCollectionForFolder, ConvertTo-CMFolderPath}
Script 1.4.4 PackageManagement {Find-Package, Get-Package, Get-PackageProvider, Get-Packa..
Script 2.2.1 PowerShellGet {Find-Command, Find-DSCResource, Find-Module, Find-RoleCap..

...

That means the module is correctly installed.
In some forums they say I should disable the import of the ps1xml file. But in this case I even don't see anymore the CMLimitingCollection module.

Is it normal that the file "CMLimitingCollection.Format.ps1xml" is empty ?

Thank you in advance for your answer.
