Package UE4 does not works

Hello, english it is not my first language, but I will try,

I´m new at this program, I have been trying to learn it by myself since the last 4 months, I was doing it good, but sometimes you have problems like this one.

I followed a tutorial for making a scanner, or kinda, it has post process effects with a volume and a custom depth stencil, when It all was ready, and working, I packaged it to android, its a mobile project, but when I ran it, this appears.

I dont know who to manage it, its really frustrating, please help me!

Thanks for reading me, have a nice day!
