ComputeOnDesktopYolo CompileXaml task returned false but did not log an error

[georgeb4]

When I try building the ComputeOnDesktopYolo sample, I was originally getting an error code of WMC9999 with the description "Exception from HRESULT: 0x80070003" and the file in question was Microsoft.Windows.UI.Xaml.Common.targets within the Visual Studio 2019 files. When I click on the error code, the Visual Studios documentation site "couldn't find what you were looking for." However double clicking on the error itself brings me to a "CompileXaml" task on line 266.

I tried using the fix by utrav in their issue posted on 5/2020 in which they moved the contents of LoadModelAsync() into MainPage() in the file MainPage.xaml.cpp. It wasn't the exact issue I was encountering but figured it was worth testing, and now I'm getting two errors:

The first error doesn't make a whole lot of sense given that the entire script is "#include pch.h". The second error occurs in the same file as what I encountered in the first build attempt, also in a "CompileXaml" task, albeit on line 415 this time.

Since the small change I made to MainPage.xaml.cpp leads to a different error in the same file in another CompileXaml task, I believe that there's either something wrong with Microsoft.Windows.UI.Xaml.Common.targets as a whole, or the CompileXaml tasks specifically, but I have not been able to find a good resource for diagnosing the problem. For reference, I am using Visual Studio 2019 (16.11.23). Any help would be very appreciated.
