Every time I run to debug app on my Nexus 6P (Android Oreo), the app will get deployed, starts briefly and then exits and Visual Studio (2015) will stop debug process and show following message

Android application is debugging.
Couldn't connect to logcat, GetProcessId returned: 0

Checking Logcat shows lots of errors, 2 of which are predominant

and the 2nd and most dominant error is
