Exception parsing MOF file '...\MSFT_AADCrossTenantAccessPolicyConfigurationPartner.Schema.mof':The given key was not present in the dictionary..

Description of the issue

I recently upgraded my install of Microsoft365DSC from version 1.25.903.1 to 1.26.318.1.

I've got composite resources for our server roles, compiling using Windows PowerShell 5.1; one of the composite resources includes various instances of the following Microsoft365DSC resources:

• AADGroup
• AADAdministrativeUnit
• EXODistributionGroup
• EXOManagementRoleAssignment

I've put some sample configurations below to give you an idea of what's happening, although I can't reproduce this outside of the composite configuration.

When I update the Import-DscResource -ModuleName Microsoft365DSC -ModuleVersion 1.26.318.1 command in the composite resource to the latest version, and try to compile, compliation fails with the following error:

Exception parsing MOF file 'C:\Program Files\WindowsPowerShell\Modules\Microsoft365DSC\1.26.318.1\DSCResources\MSFT_AADCrossTenantAccessPolicyConfigurationPartner\MSFT_AADCrossTenantAcce ssPolicyConfigurationPartner.Schema.mof':The given key was not present in the dictionary..                                                                                                 
    + CategoryInfo          : ParserError: (:) [], ParseException
    + FullyQualifiedErrorId : ExceptionParsingMOFFile

If I put ModuleVersion back to 1.25.903.1, then the compilation process works perfectly.

Please note that I am not using MSFT_AADCrossTenantAccessPolicyConfigurationPartner in the configuration at all!

Any ideas? I'm stumped!
