Shipping Build of Android Game crashes after Splash Screen

So yeah. When I launch my app from the editor, the game runs without a problem. Once I try to create a shipping build and install it on my device, it crashes after the Splash Screen. I have run adb logcat but it doesnt really contain any information that help me. Also, no UE4 logs are written on my device.

What can I do to find out what goes wrong?

Nativization of Blueprints seems to have caused the issue. I disabled it and now it works.
