When I am controlling the spaceship, it is unable to pass through the ring.

If your spaceship is unable to pass through the ring, try these solutions:

Getting used to VR controls
If you're new to VR games, the controls may take some practice. Continue playing for a while to become familiar with the controls. You can also turn off dichoptic mode while you adjust to the VR environment.

Controller tracking issue
Your controller may be outside the sensor tracking area. Hold both controllers at eye level and confirm that the spaceship is visible and responding to your movements.
