Projects crash on Android when trying to load mips

Projects crash on Android when trying to load mips

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.
