APPX_E_INVALID_PACKAGING_LAYOUT
APPX_E_INVALID_PACKAGING_LAYOUT means that the packaging layout file supplied to the build workflow is invalid. A layout describes how source files and package content are arranged for package creation.
How to resolve it
- Validate the layout XML and paths against the packaging tool and target package type.
- Check that mappings refer to existing files and that package destination paths are valid and unique.
- Regenerate layout input from the build system when a manually edited file diverges from the package contents.
Use a reproducible packaging command so the layout and final package can be audited together.
