Xamarin Android app crashes on android just after launch. Missing MonoRuntimeProvider

I uninstalled Xamarin on Mac. Then re-installed it. 6.1.4 (Build1). Now I created a new Solution. With Portable Class Library selected. Then I compiled. Then I installed on simulator running on same machine. But at the launch itself the App failed. Then I checked Application Output. Below is the log. I am not able to proceed. Please help. I checked: "Xamarin.Android API-23 Support" and "Mono runtime" are installed on the simulator android. (Uninstalling these components also did not solve)

Thanks in advance.

Below is the log:

am start -n "in.test.buttonlogger/md50a143af76fade5fdcdfca266ac349d28.MainActivity"
Starting: Intent { cmp=in.test.buttonlogger/md50a143af76fade5fdcdfca266ac349d28.MainActivity }

When you experience this issue, the normal solution is to simply edit the AndroidUseLatestPlatformSdk property in your .csproj file for the given project to false as follows:

<AndroidUseLatestPlatformSdk>False</AndroidUseLatestPlatformSdk>

If that doesn't work, then try disabling Shared Runtime in the Project Properties under Android Options.

As a last option, you can also try to decrease your Target Framework in the Project Properties under General.
