Debugging UWP app hangs on Xamarin.Forms.Forms.Init(e) on Windows Insider Build 17025

I filed this with the Windows Insider Team, but it seemed like I should post it here as well:

My Xamarin UWP app won't debug on build 17025. It hangs on the call to Xamarin.Forms.Forms.Init(e) during the bootstrapping phase. To troubleshoot, I created a new blank Xamarin app and tried to debug it. This app also appears to hang during the call to Forms.Init(). Both apps will still debug when deployed to my UWP mobile device running 15063.

I will try reverting back to the previous insider build to see if this is an issue only with build 17025.
