Hey everyone, I figured this out. More truthfully, the guy at RenderHeads that answered my post figured it out.
Under Plugins/Android/Libs/arm64-v8a, highlight each file in the inspector. Make sure the file is targeted for Android and ARM64. None of the files in my folder were targeted.
I also made sure I was only building for ARM64. Somehow I'd gotten ARM-7 checked too.
Built and deployed without problems.
Just passing this along, really. The guy to thank is AndrewRH at Renderheads.
Have fun!

I'm getting the error "Unable to find libc" with 2018.3.3. It happens during app startup, and the app eventually crashes with no other useful error messages.
