Looks like PSSA can't be loaded (which is strange since it's bundled with the extension) and then we don't handle the load failure properly

@danielfeiler Can you report the output of the following in the Integrated Console:

Import-Module PSScriptAnalyzer

[danielfeiler]

@rjmholt of course:

PowerShell Integrated Console

PS C:\Users\danielfeiler> Import-Module PSScriptAnalyzer
Import-Module : The specified module 'PSScriptAnalyzer' was not loaded because no valid module file was found in any module 
directory.
At line:1 char:1
+ Import-Module PSScriptAnalyzer

    + CategoryInfo          : ResourceUnavailable: (PSScriptAnalyzer:String) [Import-Module], FileNotFoundException
    + FullyQualifiedErrorId : Modules_ModuleNotFound,Microsoft.PowerShell.Commands.ImportModuleCommand

PS C:\Users\danielfeiler> 

[rjmholt]

Hmmmm, that's very odd.

Have you altered $env:PSModulePath maybe?

Can you tell me what the following output:

• gmo -list PSScriptAnalyzer
• gci ~\.vscode\extensions\ms-vscode.powershell-2019.5.0\modules
• $env:PSModulePath

[rjmholt]

Also you should be able to fix this immediately with Install-Module PSScriptAnalyzer -Scope CurrentUser

[SydneyhSmith]

@danielfeiler were you able to resolve this issue with @rjmholt 's suggestion above?

[SydneyhSmith]

Going to go ahead and close this as resolved but will re-open if you are still facing this issue--Thanks!
