InvalidOperationException: Sequence contains no matching element

I encountered the following error message:

```
InvalidOperationException: Sequence contains no matching element
System.Linq.Enumerable.First[TSource] (System.Collections.Generic.IEnumerable`1[T] source, System.Func`2[T,TResult] predicate) (at <3f2ee08277b24b2380a7e1ec14a64598>:0)
FastScriptReload.Runtime.AssemblyChangesLoaderResolver.Resolve () (at Assets/FastScriptReload/Scripts/Runtime/AssemblyChangesLoaderResolver.cs:23)
FastScriptReload.Editor.FastScriptReloadManager.Update () (at Assets/FastScriptReload/Scripts/Editor/FastScriptReloadManager.cs:424)
UnityEditor.EditorApplication.Internal_CallUpdateFunctions () (at :0)
```

Start in Assets/FastScriptReload/Scripts/Runtime/AssemblyChangesLoaderResolver.cs at line 23, then trace how FastScriptReloadManager.Update() at line 424 calls Resolve(). Reproduce the reported Unity Editor update failure and identify why no matching sequence element exists; done means this path no longer raises the reported InvalidOperationException.
