Arm64 error on a new project export android

Hi all I am trying to export a game to android to use arm64 with IL2CPP and it is giving an error. I am using Unity 2019.3 . I have looked in this forum and none of the fixes are working for me. I am on a mac and this isn't working out of the box on a nee project. Is this a bug or what? I will post the log below. Please help if you can. I really need to get this working.

Error 1

I have also issue with Unity 2019.3 although I am on PC., however the mine is different - I can build both 32 & 64 apks,however, once I tried to either it simply fails - it cannot even show unity splash screen.
I believe the root cause is switch to Android NDK 19, since I have the very same project compiled flawlessly under 2019.2, which works with NDK 16. So in my case the only difference between two unity projects is NDK version.
Unfortunately you cannot force 2019.3 to work with NDK 16. In fact setup 2019.3 to work with downloaded by UnityHub NDK is also a problem, as you can see here - https://forum.unity.com/threads/solved-android-ndk-missing.689122/
I would say, this Unity version is not able to compile a proper Arm64 apk.
