Just resolved this one myself. I had to untoggle x86 Target Architecture in Player Settings -> Other Settings. Someone mentioned getting updated NDK or split APKs by target architecture if you have to build x86 still. In my case I did not.

This worked for me on one branch, not on another - very inconstant :( If only the il2cpp output for clearer as it is invoked by unity..

Same here, I've tried for a few days now to get a working ARM64 build - using many different version of Unity/PK/SDK combinations

I've tried the following: Stages: NOTE: RUN UNITY HUB AS ADMIN - if you don't get a 'give permissions confirmation screen' Run Unity directly as admin from it's location. NOTE: Unity 2018.2.1f1 Requires version 28 of SDK, r16b of NDK and JDK 1.8 (Version 8, Default loc: C:\Program Files\Java\jdk1.8.0_221) NOTE: Delete Plugins folder in assets if you have used it, this causes a build location error for some reason...(https://stackoverflow.com/questions/54194428/unityeditor-buildplayerwindowbuildmethodexception) NOTE: Delete all .sln files in the UnityProject (https://answers.unity.com/questions/1574025/build-fail-unity-201830b9.html) NOTE: Delete .vs folder (Hidden) NOTE: Make sure build output location is as simple as possible, recommmend root C/D drive NOTE: Make sure Gradle build is selected in player settings, less than this will cause errors NOTE: Mya be advisable to set Minify options under player settings to None NOTE: Make sure you uninstall packages that prevent a build such as : NUnit Unity Collaborate Test Framework

NOTE: If build failure still, try deleting Library directory - it will be rebuilt considering above changes
