Unique Error ? - KeyNotFoundException

Hello,

I don't have much experience reading logs, and need assistance with some build errors, please.

I am building an Admob test app starting from a hello world, clean working build.
Compiles fine.

I install the GoogleAdmob asset package for unity.
Play works fine, but build or build and run is failing.
This build fails on both 5.4.5p5 and 2017.3 in either gradle or internal build modes.

Gettings a tools error for the SDK, I have verified all Android studio installed packages are present, and all Androidmanifest.xml files match the targetminSDK of 16 and the targetSDK of 25.

Getting a key not found exception, here is the stack:

KeyNotFoundException: The given key was not present in the dictionary.

All I cant find online about keynotfound pertains to objects in scene not being present or accessible, this is referring to a system.string, and I have no idea how to fix a missing system.string in dictionay.cs. That path does not exist on my system, neither does dictionary.cs

Can somebody please help with resolving this error?

Thank you.

Ebones.

 

I reported a native crash on Google Play test devices to Unity a few months ago, sent my app files and never heard back ANYTHING, and they have my entire project.

Not really wanting to do that again, as I also have no record of the email being sent, since it was done through the unity editor reporting tool.
