User already Logged In

Hello Guys,

I have this using .Net desktop app

Dim mfApp As New MFilesClientApplication()
Dim vaultConnection As VaultConnection = mfApp.GetVaultConnection("Doc Vault")
Dim vault As Object
vault = vaultConnection.LogInAsUser(120760, CStr("Vc@Re@2025!!"), CStr("Crusader"))

But I kept getting "You are already logged in to this vault." (0x80040087)

My Plan was to get all files downloaded out of M-file and also to be able to upload files using COM API
