Devolutions Launcher error when using 2FA

Newer install here, still getting comfy. When using 2FA (google in this case) logging into the launcher generates an error:
System.AggregateException: One or more errors occurred. ---> System.NullReferenceException: Object reference not set to an instance of an object.

Launcher and DPS are both current versions. Turning 2FA for the user to none = no errors.
