UIApplication Assertion Failure in Xamarin.iOS App
<p>I was in the middle of developing an update to my Xamarin Forms app, but when I debugged it on my iPhone, it crashed immediately on startup with the following message:<br></p>

<pre><code>Assertion failure in -[UIApplication_runWithMainScene:transitionContext:completion:], /BuildRoot/Library/Caches/com/apple.xbs/Source/UIKit/UIKit-3600.5.2/UIApplication.m:3679
</code></pre>

<p>It was previously working fine, but now I can't run the app on my phone anymore without this crash.  I have rebuilt several times and deployed from different computers, but nothing helps.  How do I fix this issue?</p>

<p><strong>Edit:</strong><br>
Before this started occurring, I had made some additions to the code.  Unfortunately, after removing all of my changes, this issue is still plaguing further development.  Any help or resource that might lead me to a solution will be greatly appreciated.</p>
