Issue Description

After installing the latest preview, I got the following errors:

1. PowerShell Intergrated Console:
   An error occurred while starting PowerShell Editor Services:

Unable to load one or more of the requested types. Retrieve the LoaderExceptions property for more information.
   at System.Reflection.RuntimeModule.GetTypes(RuntimeModule module)
   at System.Reflection.Assembly.GetTypes()
   at Microsoft.PowerShell.Commands.AddTypeCommand.LoadAssemblyFromPathOrName(List`1 generatedTypes)
   at Microsoft.PowerShell.Commands.AddTypeCommand.EndProcessing()
   at System.Management.Automation.CommandProcessorBase.Complete()

2. After some time I got that error message:

@TheUntouchable This might be caused by anti-virus, which we'll have a fix for in the coming release. See #1831

However, the specific assembly/type loading problem looks like it might not be caused by that. To get the reason why it's failing, you'll need to collect a fusion log using these instructions. That should give you a pretty good explanation of precisely why the assembly isn't loading. Please try that and let us know here.
