Fixed the Win32 startup path initialization in fe_args to avoid blindly calling g_path_get_dirname(argv[0]) when argv may be missing/invalid in subsystem:windows launch contexts (like URL handler launches).

Browse Source 
Updated logic to prefer g_win32_get_package_installation_directory_of_module(NULL) first, and only fall back to argv[0] when argc > 0, argv != NULL, and argv[0] != NULL, preventing null/invalid pointer access during startup.
