Just updated VIVE Console today from the previous version to 2.0.20.2 and now I get this error:
Failed to suggest bindings for interaction profile '/interaction_profiles/htc/vive_cosmos_controller' with result 'XR_ERROR_PATH_UNSUPPORTED'.
Everything was working fine yesterday, wanted to make sure it wasn't my Unity project so I hopped on an earlier commit where I knew everything was working and it's broken there as well.
Unity 2020.3.30f1, XR Interaction Toolkit 2.0.0, XR Plugin Management 4.2.1.
I see the controllers working just fine in Viveport and SteamVR home.
