Hello @Speed-Milker, we're using one issue report per unofficially supported game title, so I've gone ahead and transferred this issue report to https://github.com/ValveSoftware/Proton/issues/8413#issuecomment-4478062448.

Compatibility Report
System Information
I confirm:

Symptoms
Upon first launch of the game ('Force the use of a specific Steam Play compatibility tool' was NOT enabled in the 'Compatibility' sub menu under 'Properties' during first attempt to launch) the EA app was installed in the prefix successfully and the game launched and was in a playable state (was able to change settings in menus, start a playthrough). After closing the game and attempting to relaunch later, issues began.
The game would not launch, EA app would not open and the 'Play'/'Cancel'/'Stop' button in the Steam library page for Dragon Age II would change back to 'Play', indicating that the game had not launched successfully.
After searching online, I attempted to launch the game using different Proton versions (listed above). These had varying levels of success and were inconsistent upon each attempt to start the game. More often than not the EA app would try to install again, and would fail at various stages of the process.
When the EA app would install, I then encountered issues with authentication within the EA app, where I would receive an error message saying something to the effect of "We cannot authorise your copy of Dragon Age II on this device at this time".
Sometimes I was able to double click the icon for the EA app in the system tray and open the EA app, where I would receive an error saying that I could not play the game.
In my current testing (Proton Experimental and Proton 11.0 (Beta) the game fails to launch. After pressing 'Play' when I try to open the EA app it closes straight away, at which point I see the splash screen for Dragon Age II, after which the game doesn't launch. When I do not try to open the EA app, the splash screen sometimes does and sometimes does not appear. Either way the game fails to launch. This also happened when I disabled the 'Force force the use of a specific Steam Play compatibility tool' in 'Compatibility' and attempted to try again.
I have attempted multiple clean installs of the game, deleting the compdata prefix for Dragon Age II and clearing my download cache and reinstalling again. This appears to have had no effect.
PS: From extensive research and reading of posts online, I suspect this issue is also relevant for most if not all games that require the EA app to run.
