Unreal Engine Issues and Bug Tracker (UE-40927)

Description

Projects that are deployed in the Debug configuration crash when trying to load mips on the Android device.

I do not see this issue when launching a project onto Android using the Test configuration.

Steps to Reproduce

1. Open UE4Editor
2. Create a new First Person Blueprint project
3. Select Edit > Editor Preferences > Play > Play on Device
4. Set Launch Configuration = Debug
5. Close the Editor Preferences
6. Select the drop down arrow to the right of the Launch button
7. Select the Android device in the Launch On menu

RESULT:
The project deploys to the Android device then crashes while loading.
