Could not load file or assembly 'Newtonsoft.Json, Version=9.0.0.0.....

[desireewilliams]

With the release of version 2.0.1911.1, I updated my existing module in order to get some of the newer cmdlets that were released. Connect-PartnerCenter still works (well, sort of. The -ApplicationId option is no longer valid, but I could get it to connect so that's neither here nor there).

However, when I run any other command I get:
Could not load file or assembly 'Newtonsoft.Json, Version=9.0.0.0, Culture=neutral, PublicKeyToken=30ad4fe6b2a6aeed' or one of its dependencies. The system cannot find the file specified.
At line:1 char:1

• Get-PartnerCustomer

•   + CategoryInfo          : NotSpecified: (:) [Get-PartnerCustomer], FileNotFoundException
    + FullyQualifiedErrorId : System.IO.FileNotFoundException,Microsoft.Store.PartnerCenter.PowerShell.Commands.GetPartnerCustomer
  
  

The two cmdlets that I tested this on are Get-PartnerCustomer and Get-PartnerCustomerUsageRecord. I have also replicated the behavior on a system that has never had the PartnerCenter module installed on it.

If I open the folder with the module files in it, there is a Newtonsoft.Json.dll available. However, it is not the version mentioned above:

@desireewilliams would it be possible for you to share the output from Get-Module after you have loaded all the modules had loaded when you encountered this error?

@IsaiahWilliams here is both the error and the modules from a new instance of PowerShell

Here's a text version of the Get-Module

I'm experiencing a similar issue. I'm able to Connect to Partner Center, but not perform a Get-PartnerUser command. Screenshot attached:
