Hey ,
Looking over the warnings on the screenshot provided, it looks as if you’re having trouble with a specific blueprint widget. Please look over the blueprint for ‘Widget3DPassThrough_Translucent’ and ‘Widget3DPassThrough_Translucent_OneSided’. I’d also suggest looking through any other errors that may be on that message that aren’t showing up.
Also are you trying to launch the project from 4.8.3 source and 4.8.2 source or is 4.8.2 binary (from the Epic Games Launcher)? Are you able to package any other project/template from either version of the Engine? Is this only happening with one of your mobile devices or all of them?
Here are some links that may help you with the issue you’re running into:

- [Mobile Game Development][2]
Looking forward to hearing back from you, thanks!
