Android Black Screen/Not Responding

Im using version 4.10. My project doesn’t have any 3d assets, only UMG logic that I need to test. Its working fine on PC. Ive also checked all the maps/modes and they are all fine. When I run it on the phone the splash screen appears followed by a black screen and then a not responding message. I can play tappy chicken on my phone so it should be possible to load a umg widget easily. I have also tried migrating to a clean project but the results are the same.
