The command returns null because [System.Environment+SpecialFolder]::ApplicationData) is mapping to home/.config and if home/.config doesn't exist, it returns null

I believe the following needs to be modified in import-config.ps1

1. passing a DoNotVerify option to getfolderpath
2. Create the directory if needed

$AppDataDirectory = Join-Path ([System.Environment]::GetFolderPath([System.Environment+SpecialFolder]::ApplicationData,[System.Environment+SpecialFolderOption]::DoNotVerify)) 'MSAL.PS'
[system.io.directory]::CreateDirectory($AppDataDirectory)
$Path = Join-Path $AppDataDirectory $Path
