Something when wrong when trying to initialize the Oculus headset.
One reason could be that you physically connected the Oculus to a DVI port using a HDMI-to-DVI connector. Try plugging your Oculus directly into a HDMI port.
Another reason could be that you previously ran steamVR with a different headset (e.g. you switched from Vive-HMD to an Oculus-HMD) while steamVR was running. Quit steamVR and try running the game again.
