Hi there, I have just switched to 2019.3.0f1 and since I am working on mobile game, I tried to compile my project, which so far runs smoothly on 2019.2.14f1. My OS is Windows 10 home 64.
The first bummer I have got is the one described here - Android NDK missing . Anyway I thought I fixed it, however UnityHub basically is not able to download the proper NDK, so I have to download it manually from the provided link and to place it into separate folder.
Then I built the project. I use IL2CPP, ARM64, ARMv7, split APKs by target architecture. Again, please note all these work just fine under 2019.2.
Once the compilation process completed, I install ARM64 on my device and try to run it. I can see a short screen blink and the app closes - I cannot see even the Unity splash screen.
Same goes with Armv7.
So basically I cannot build an Android app with Unity 2019.3.
Post your logcat logs.

It seems you’re using a native library that the Android Runtime is unable to load. Try building and running an empty new project on that device and see if it crashes too. If it doesn’t, the problem lies in your code.
@TommyTheITGuy - I spent some time today and created a brand new Unity project with Unity 2019.3.0f1 - just a 3D project, no other extras.
Below are my Player Settings:
again - the app builds and then fails on load - w/o even show me an Unity splash screen.
Attached (mobile.txt) is the collected logcat output.
One thing need to mention - I set manually NDK path as well as Android SDK, since during the install via SmartHub Unity didn’t able to find NDK.
So basically, this is an empty project and as you can see it fails as well.
