This exact error happens with other modules, including Azure AD, in PowerShell Core 6.2.1 even with version 4.8 of the .Net framework installed. You can resolve it in your session by manually loading System.Windows.Forms at the command line:

[System.Reflection.Assembly]::LoadFrom("C:\Windows\Microsoft.NET\Framework\v4.0.30319\System.Windows.Forms.dll")

prior to Import-Module -name [your module with Windows Forms dependency] but until this is resolved you may also want to add the .Net libraries to your path, and maybe even that module to the GAC.

That leads to more of the same when I try to import the PartnerCenter.NetCore module:

Import-Module : Could not load file or assembly 'Microsoft.IdentityModel.Clients.ActiveDirectory, Version=3.19.8.16603, Culture=neutral, PublicKeyToken=31bf3856ad364e35'. Could not find or load a specific file. (Exception from HRESULT: 0x80131621)
