Question Vuforia Dataset could not be loaded and cannot be activated

Hello, community !

I'm trying to work with Vuforia in Unity.

Vuforia v9.8.8
Unity v2021.1.3.f1
Laptop: HP Envy

After I'm importing the Vuforia Engine plugin and trying to launch the scene, I'm getting the following errors:

1. Dataset YoutubeTutorial could not be loaded and cannot be activated. UnityEngine.Debug:LogError (object) Vuforia.DatabaseLoadARController:LoadDatasets () Vuforia.VuforiaARController:StartAfterInitializationCompleted () Vuforia.VuforiaARController:Start () System.DelegateynamicInvoke (object[]) Vuforia.DelegateHelper:InvokeDelegate (System.Delegate,object[]) Vuforia.DelegateHelper:InvokeWithExceptionHandling (System.Action) Vuforia.VuforiaBehaviour:Start ()

Can somebody help me to solve this ?

Have a great day !
