Unable to run Apps. Assembly with same name is already loaded

Product: PowerShell Universal
Version: 5.0.6

I have tried to run the built in/module provided apps and I have tried building my own with the most basic code example from the website. Apps either refuse to start (ActiveDirectory app) or give me this error:

Assembly with same name is already loaded System.Management.Automation.CmdletInvocationException

The ActiveDirectory

The example code that I used was:

New-UDApp -Content {
   New-UDButton -Text 'Click Me' -OnClick {
       Show-UDToast "Ouch!"
   }
}

In the web browser I see this error for custom apps:
One or more errors occurred,Object reference not set to an instance of an object.

The ActiveDirectory app displays this error in the browser:
The term '' is not recognized as a name of a cmdlet, function, script file, or executable program.
Check the spelling of the name, or if a path was included, verify that the path is correct and try again.

System.Management.Automation.CommandNotFoundException: The term '' is not recognized as a name of a cmdlet, function, script file, or executable program.
Check the spelling of the name, or if a path was included, verify that the path is correct and try again.

The included documentation has a similar issue as shown in this screenshot:



I am happy to provide more information if you can tell me where to look.
