Issue Launching Titanfall 2 via Steam and EA App

I am experiencing an issue when trying to launch Titanfall 2 Deluxe Edition, purchased on Steam. Every time I attempt to start the game, I receive an error stating that the game cannot be launched because the EA App is trying to download it again, even though it’s already installed through Steam.

Here are the steps I have already tried to resolve the issue, without success:

1. Clearing the EA App cache.
2. Reinstalling both EA App and Steam.
3. Verifying the integrity of the game files via Steam.
4. Completely uninstalling and reinstalling the game.
5. Running both EA App and Steam as an administrator.

I have also confirmed that the installation path in the Windows Registry is correct, but the issue persists.

Could you please advise me on how to resolve this problem?
