Verifying download and crash

I created a GearVR app using UE4. I am running the app after uploading it to the store build for distribution, the app will close with the following video
 Does anyone know why?

Ps.
My UE4 version is 4.23

I solve my problem!

The Verifying download window was due to the build option of the UE4, and the app crashing was due to the shipping option!
