If you're facing the issue where the EA Application can't detect the game path for A Way Out from Steam, causing it to validate every time you launch the game, here's a simple fix you can follow:

Press START, type "Regedit" in your search bar and press Enter

In the Registry Editor, in the left side of the panel, navigate and open the following path:
HKEY_LOCAL_MACHINE\SOFTWARE\Hazelight\AWayOut

On the right-hand side, locate the entry named Install Dir. Double-click on it to open the editor.

Paste the directory path where A Way Out is installed via Steam. For example, in my case it is:
D:\SteamLibrary\steamapps\common\AWayOut
If your Steam library is located elsewhere, be sure to adjust the path accordingly (if you don't know how to find it, in the next step I'll also explain that).

IF YOU ALREADY KNOW THE PATH TO USE IN THE PREVIOUS STEP SKIP THIS SECTION.
Open your Steam library, find A Way Out in the left side column and click on it with the right mouse button. Then go to 'Manage' and 'Browse Local Files'. Now simply copy the path of the folder you're in from the navigation bar in the upper area of the window.

After entering the correct path, simply press OK and close the Registry Editor.

This should resolve the issue with the EA Application not finding and mapping the game path from Steam! Just start the game from Steam and now it should work fine.
