Xamarin Crashing at EntryPoint

Xamarin keeps crashing at the app entry point, it throws an EntryPointNotFoundException even in the basic hello world project. What is my issue?

I've tested the app on a couple emulators and some physical devices, with different versions of Android, the app ran on all the emulators and physical devices prior to the latest Xamarin Studio update
