Hi @rvejendla, could you please specify how you are initializing the Tobii XR SDK?
If using the TobiiXR Initializer prefab, and if so with what settings and if you are somehow referencing it in code somewhere.
Are you able to get ET data from the regular SDK using TobiiXR.GetEyeTrackingData?
What Pico SDK are you using and lastly, what happens when you create a new project and only import the necessary SDKs and Ocumen and if it works there, following our getting started and installation guides:
