Errors with databases linked to Windows Accounts

[fullenw1]

When I register a database with a Windows Account in addition to the Master password I get this output:

PS> Register-KeepassSecretVault -Path 'C:\MyPath\MyKeepass.kdbx' -Name MyKeepass -UseWindowsAccount -UseMasterPassword
WARNING: [13:52:29][Test-SecretVault] Exception calling ".ctor" with "0" argument(s): "Operation is not supported on this platform."
WARNING: [13:52:29][Test-SecretVault] Unable to open connection to the database
Register-KeepassSecretVault : A parameter cannot be found that matches parameter name 'Name'.

+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : InvalidArgument: (:) [Register-KeepassSecretVault], ParameterBindingException
    + FullyQualifiedErrorId : NamedParameterNotFound,Register-KeepassSecretVault

If I do the same with a database which does not need a Windows Account authentication, I get no error.

Furthermore, despite the error message the database seems to be registered anyway.
It appears in the list returned by Get-SecretVault.

PS> Get-SecretVault

Name          ModuleName                       IsDefaultVault
----          ----------                       --------------
LocalComputer Microsoft.PowerShell.SecretStore True
MyKeepass     SecretManagement.KeePass         False

However, when I try to unlock the vault, I get this error:

PS> Unlock-SecretVault -Name MyKeepass

cmdlet Unlock-SecretVault at command pipeline position 1
Supply values for the following parameters:
