Windows Remote Desktop Client "We Couldn't Authenticate You" Error

Question

When I run the Windows Desktop Client on many of the desktops in my environment, I get the attached error when I click the subscribe button.  The web client works fine from these computers.  This is using the newest client.  I get the same thing if I put in the feedurl.  This error immediately pops up, it never even asks me to login.  The Windows Desktop Client works from other computers.

This issue was on Citrix Server 2016 Session Hosts. The solution ended up being to run this powershell script at login:
if (-not (Get-AppxPackage Microsoft.AAD.BrokerPlugin)) { Add-AppxPackage -Register "$env:windir\SystemApps\Microsoft.AAD.BrokerPlugin_cw5n1h2txyewy\Appxmanifest.xml" -DisableDevelopmentMode -ForceApplicationShutdown } Get-AppxPackage Microsoft.AAD.BrokerPlugin

This only resolved the issue for published desktops, not for published apps.
