[SOLVED][ARCore] NDK Build Error on HelloARSample project?

So I’ll try this again,

Cleaned and Re-installed everything Visual Studio, re-built the engine from source. reloaded New HelloARSample project. SAME ERROR every time.

It looks like it’s something to do with the NDK build. so i tried downloading a newer beta and stable folder of NDK and loading that in the Project Settings/Android SDK section. NO DICE!

​​​​​Any Help here devs?

Visual Studio 2015
Pixel XL
Windows 10

UPDATE: So i found a thread with someone getting similar issues with another plugin in their SDK, and they fixed it by removing spaces from the SDK location. I did the same with my NVPACK location

old location of SDK:
D:/Games/Epic Games/NVPACK/android-ndk-r12b/ndk-build.cmd
location that worked:
