Had the exact same error message when attempting to sideload a packaged WinUI 3 app on Windows 11. It worked as soon as I installed through the MSIX Troubleshooter as suggested by Bogdan Mitrache. I haven't hit the error with this particular app since after, even when using the regular App Installer.
None of the suggested locations of the Event Viewer were any helpful beyond that error message, The only additional intel I could find was "The last successful state reached was UndockedDEHEvaluated. Failure occurred before reaching the next state Approved. hr: 0x8000FFFF".
