We’re having some issues with Unity as a Library with the 2020LTS version of Unity when importing into an android application. We’ve exported the build out and added the :unity library as intended on our android build and now we keep getting the attached message when ever we attempt to launch the unity player. We’ve also tried with both the 2020.3.5f1 and 2020.3.4f1 versions with no luck.
We’ve had this same implementation working successfully with the 2019.4.19f1 build but since attempting to update to the 2020LTS build we can’t get things to run. We’re just trying to figure out what is causing the updated IL2CPP issues.

Build
Success (unityLibrary\src\main\jniLibs\arm64-v8a\libil2cpp.so, unityLibrary\src\main\jniLibs\armeabi-v7a\libil2cpp.so were created)
As you see from screenshot, in build output, there’s a task
> Task :unityLibrary:BuildIl2CppTask
the full output is

WARNING: The option 'android.enableR8' is deprecated and should not be used anymore.
It will be removed in a future version of the Android Gradle plugin, and will no longer allow you to disable R8.

Can you do the same as me, and check if empty project with your overridden launcher build.gradle works?
Can you copy paste your build output? (The one which doesn’t work)
Alternatively try attaching unityLibrary build.gradle and root build.gradle
