Why is my Gradle Failing on my Unity Android Build?

I used to use 'Internal' option to build my Android Version but in Unity 2019 there is no option.

When trying to build my Android version I get the following errors:

D8: Program type already present: android.support.annotation.FractionRes UnityEngine.GUIUtility:ProcessEvent(Int32, IntPtr)

FAILURE: Build failed with an exception. * What went wrong: Execution failed for task ':transformClassesAndResourcesWithR8ForRelease'. com.android.tools.r8.CompilationFailedException: Compilation failed to complete * Try: Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights. * Get more help at https://help.gradle.org BUILD FAILED in 19s
