Log detailing load error

I encountered the following problem while attempting to setup the dev environment for https://github.com/HTBox/MobileKidsIdApp

The project requires me to download and install Visual Studio 2015 and Xamarin on Windows 10. Having downloaded and installed Visual Studio 2015 Community Edition (Update 3), I updated the included Xamarin tools to the following versions:

After doing so, Visual Studio 2015 freezes when opening the solution file for the project. Specifically, I can see that VS freezes when loading the iOS project (the Android project is able to load). I checked the Xamarin error log and found the following entry:

Xamarin.VisualStudio.IOS.XamarinIOSPackage|Warning|0|Initializing Xamarin.VisualStudio.IOS.XamarinIOSPackage.
Xamarin.VisualStudio.MsBuild.ProjectBuildTracker|Error|0|Cannot start build tracking. Project is null.

After googling the problem, I found some users reporting that deleting the bin/obj folders and .vs folder fixed the issue for them. I did so, but Visual Studio still hangs for me. I found another bug on this site that sounds similar to my problem, but it concerns loading Android projects (https://bugzilla.xamarin.com/show_bug.cgi?id=60080). Please let me know of any additional details and files I can attach/provide.

As you mentioned, bug 60080 is related to Android projects, but we have also found another issue that causes VS to hang when loading iOS projects. 

In order for us to confirm whether you are experiencing this same issue or a new one, can you provide the dmp file gathered by following the guide below? Thanks!
