UWP Release mode builds fail sporadically in CI

The issue

When the CI compiles the Strix Music app in release mode, there's a high chance that release mode will fail and need to be rerun. The error message is:

The solution

Build locally in release mode and find/fix the cause of the build error. Use Visual Studio and set the build output level to at least "Detailed" to get the most useful information.

#184 contains all of our attempts and findings so far.

#201 might be able to help us sidestep the issue entirely by having build validation done on the contributor's machine(s).
