Hi @bfalandays sorry to hear about your issues.
Could you kindly clarify which version of TobiiXR is being used, since we made a change in the ControllerManager class. The ControllerButton enum was moved out of the ControllerManager class, meaning that references that were previously ControllerManager.ControllerButton should now just be ControllerButton
If this is not the issue, trying to delete all Tobii XR related things from the project and importing the latest version to see if this fixes it.
