The major changes are
Ver1.2 PCVR is now available in Single Pass.
Ver1.5 Network function added
Ver1.64 Unity version was raised.
If we can find the system that causes the problem, we may be able to solve it.
Try running the game on the desktop without launching Oculus with the current version (1.66).
If you can now launch it, you will know that there is a problem with the VR system.
