Android App stuck in SplashScreen, LaunchLoop

I’m completely stuck with a problem. I am trying to test my project/app on my android device.
However most of the time it will get stuck on the UE4 splash screen, then close and instantly start again without reaching any map.

Some few times it worked, but I don’t know what was different. Same procedure basically.

I tried getting logs or debug information via Android Studio and the logact tool inside, without success.

I really hope someone can guide me in the correct direction and any help is appreciated!

Best regards,
