Issues Regarding GazeTarget.cs: Game Plays Flawlessly in Editor, but not in Build

I'm close to completing my first Gaze and Click simulator, which simulates an interview with two virtual personalities. 

The game was made with Fungus, a free visual flowchart creator from the Unity asset store.

In the editor I can choose my option with the gaze pointer and select it with the A button on the right touch controller. When I build my game, the gaze cursor no longer appears, and I cannot select anything. I'm a 3D artist by trade and my coding isn't very strong, so I have trouble figuring out what the issue is.

Game Engine: Unity 2018.4.4f1
Oculus SDK: Unsure?

Output log crash report:
