Full Body Tracking not working (Movement SDK, Unity)

I am experiencing an issue where body tracking fails to start when running the Movement SDK Retargeting Sample or using the OVRCameraRig in a separate scene (like in Valems tutorial). So basically i can move and look around, but the character stays in place in its standard sitting down or T pose position.

The error message displayed in Unity is: [OVRBody] Failed to start body tracking with joint set FullBody.

Setup Details OS: Windows 10
Unity Version: 6.000.0.41f
Headset: Meta Quest 3 (dev mode, connected via Link and all movement tracking settings turned on).
Project Template: Unity 3D Core

I tested in two plugin management setups :

Setup 1 Meta XR All-in-One SDK: 74.0.0
OpenXR Plugin: 1.14.1
Unity OpenXR Meta:2.1.0
Meta Movement v72.0.0

Setup 2 (same as in Valems tutorial)
Meta XR All-in-One SDK: 71.0.0
Oculus Plug in Meta Movement v71.0.1 In both the Meta Project Setup Tool reports XR readiness for both Android & Standalone.

Body tracking setting in the OVR manager are supported/required. 

Does anybody have an idea on why it doesn't work? Id be super grateful for any assistance you can give me.
