Getting NullReferenceException in GeNa scripts after installing Pegasus

[dixZo1337]

As the title say, I'm getting a NullReferenceException everytime I press play after installing Pegasus.

I'm running Untiy 2021.3.9f1 and the latest Version of Pegasus and GeNa.

ErrorMessage is:
 

NullReferenceException: Object reference not set to an instance of an object
UnityEditor.AssetDatabase.Contains (UnityEngine.Object obj) (at <0d6ce211ebbc47e1a35a84c3672ff58f>:0)
GeNa.Core.GeNaSpawnerExtensionEditor.OnEnable () (at Assets/Procedural Worlds/GeNa/Scripts/Editor/Extensions/GeNaSpawnerExtensionEditor.cs:33)

 

and

NullReferenceException: Object reference not set to an instance of an object
UnityEditor.AssetDatabase.Contains (UnityEngine.Object obj) (at <0d6ce211ebbc47e1a35a84c3672ff58f>:0)
GeNa.Core.GeNaRiverExtensionEditor.OnEnable () (at Assets/Procedural Worlds/GeNa/Scripts/Editor/Extensions/GeNaRiverExtensionEditor.cs:20)
