This issue also repros with WinUI 3 Desktop in WASDK 1.0. Using the ms-appx:///[libraryname]/[path-to-file] syntax instead of the path inside the library is a suitable workaround (for me at least).

Thanks for getting back to this @evelynwu-msft! This doesn’t seem to repro anymore using WASDK 1.1, closing this issue as it is fixed.
