Program crashes after trying to launch on Android

I followed the tutorial and did everything to set up and launch my game on Android for GearVR, but every time I try to launch it, it says “Loading assets for Android” for a few seconds, and then gives me a popup saying “Unreal Engine has stopped working” and closes. I’ve already tried restarting my PC and Unreal Engine, and nothing has worked. And yes, I have installed and set up everything correctly. How would I fix this?
