WiX fragment file not found: {}
Error message
WiX fragment file not found: {} What it means
bundle_windows_msi referenced a WiX fragment file path from wix_settings.fragment_paths that does not exist on disk. The MSI build cannot compile without all declared fragments, so the bundler bails with the missing path.
