The TargetPlatform is WindowsNoEditor and the build configuration is Shipping.I have trace the debugging code and find a fact that It is normal to be failed according to the source code(function FMaterial::CacheShaders() in MaterialShared.cpp)

I fixed it on Unreal 4.26.2

project settings → platforms → your platform's material quality, turn OFF Discard Quality During Cook.

I hope it works fo you too. Good luck!

This issue is present every where.
4.26.2, 4.27, UE5_EarlyAccess, UE5_Main.
I have used all above branches of engine and never got the success launch of my Android Game.
