Updated to Oreo [Android] - Now Daydream App Crashing on Launch

I have tried what has been suggested there, but now I can’t even get my project to successfully build anymore.
I keep getting this error at the very end, during the final package preparation:

UATHelper: Packaging (Android (ASTC)): ====10/13/2017 12:29:16 PM====PERFORMING FINAL APK PACKAGE OPERATION================================================
UATHelper: Packaging (Android (ASTC)): BUILD FAILED

UATHelper: Packaging (Android (ASTC)): Program.Main: ERROR: AutomationTool terminated with exception: ERROR: cmd.exe failed with args /c “D:/NVPACK/apache-ant-1.8.2/bin/ant.bat” debug -Djava.source=1.7 -Djava.target=1.7
UATHelper: Packaging (Android (ASTC)): Program.Main: AutomationTool exiting with ExitCode=1 (Error_Unknown)
UATHelper: Packaging (Android (ASTC)): BUILD FAILED

I’ve updated the SDK’s and extra files and such still busted.
Is there some other file I have to update too?
I noticed that in Step 3 my path was different, and I saw that there was an additional PublicIncludePaths to add. There was an armebai & an armeabi-v7a Is only one of these needed?
