Prefab instance problem: AuthenticationKit

Hello all,

I am receiving this error when I import the SDK into my otherwise empty Unity project:

Prefab instance problem: AuthenticationKit (Missing Prefab with guid: a41feed31bcc36541a7a9505212ddc63)
UnityEngine.GUIUtility:ProcessEvent (int,intptr,bool&)

Help would be greatly appreciated. Thanks

Hello which version of the Unity SDK are you using (and which Unity version for the project)?
