Remote desktop app hangs when opening a new process

Hi, published RemoteApps can get awkward when the application launches a child process like Excel, especially if that child window is not being surfaced correctly to the user session.

I would test:

1. Publish Excel temporarily and confirm it opens normally by itself.

2. Run the same export inside a full desktop RDP session to see whether the Excel window appears there.

3. Check whether Excel is launching hidden, waiting on a dialog, or blocked by first-run prompts.

4. Disable Office first-run/privacy prompts for the RDS users through policy.

5. Make sure the app is not launching Excel under a different user context.

If it works in full desktop but not RemoteApp, the fix is usually around how the child process/window is launched or how Office first-run prompts are handled.
