Hi @akkuashfaqueck do you mind providing us some more information on the issues you are running into?
In short, yes we have had developers that were able to use Magic Leap OpenXR and Vuforia in the same project. They were able to use the Hands interactions using MRTK3 or by using the XR Hands Interaction demo as a starting point.
For general Vuforia questions, you may want to reach out on their stack overflow category.
For General questions regarding XRI and the XR Hands Package you may want to post your question on the Unity's Discussion page
Actually I tried setting up vuforia with openXR but I could not understand how MRTK manage the scenario of Both openXR and vuforia is trying to access the camera.
