I am currently experiencing the same problem on Win10. Everything was working fine right up to the moment it stopped working.
The EA app was running in the background (minimized to taskbar) while I was watching random YouTube vids. Steam was running similarly too. PC had a BSOD. Completely unrelated to the EA app.
After restart, Steam works fine.
However, the EA App is stuck in a loop with the 'Restart App' popup. It throws up a total of 3 popups EVERY time it attempts a restart. After a few times of clicking on the 'Exit' button on 2 and restarting from 1 pop up, now it shows 2 pop ups every restart cycle. After ~50 attempts to go from 2 pop ups to 1, I gave up 😞
Even gives a popup while uninstalling the EA app. But waiting it out finally results in a successful uninstall.
Did all the thing mentioned in the thread - uninstall clear cache, delete all related files, etc, etc. Even removed all registry entries related to EA. At this point, Only option left seems to be reinstalling Windows.
Any solution available? Only EA game I have installed is ME3 for occasional multiplayer.
EDIT - Since I am crazy enough to do it, I reinstalled windows. Fresh Install, wiped my original OS drive. EA App still doesn't work. so I guess it means that it is DEFINITELY an error with the app, and not your PC.
