Access Violation Crash in Compiled VR game on projectile hit

I have a bug in my Vive VR game where in the executable version of the game, there is an Access Violation crash whenever a projectile hits an enemy. Everything works fine when I run it in the Unity Editor. I submitted a bug report two weeks ago (viewable here), but there's still been no response whatsoever.

What should I do now? The game is essentially unplayable, I have no idea what's causing it, no idea if or when I'll get a response from the Unity support staff, and since it runs fine in the editor, my debugging capabilities are very limited.

Incidentally, my projectile collision code is:

 void OnTriggerEnter(Collider other)
     {
         //print(other.tag);
         if (other.tag == "nodeSphere" || other.tag == "exclusionZone")
             return;
         if (other.tag == "enemy")
         {
             Enemy eScript = other.gameObject.GetComponent<Enemy>();
             if (eScript == null)
             {
                 Subcollider subScript = other.gameObject.GetComponent<Subcollider>();
                 eScript = subScript.parentObject;
             }
             eScript.TakeDamage(damage);
 
         }
 
         if (hitObject)
         {
             Instantiate(hitObject, transform.position, transform.rotation);
         }
         Destroy(this.gameObject);
     }

The hit object itself does not cause the crash (tested that), and if I remove the VR functionality and compile, that executable version does not crash when projectiles collide.

So again, what should I do now, since I've had no response from Unity support after waiting two weeks? Is this a problem with the SteamVR plugin (in which case I should contact HTC or Valve)? If you actually have a solution to the problem, that would be welcome too! Thanks!
