This is by design if the "Protected mode" option is on.

The first app has no HWND or interface, but can access all files.

It starts the second app in a sandbox, which can access no files. It has all windows and HWND.

The first app controls access to files for the second app. This is called "Sandboxing" and many apps now do this, especially web browsers.
