EA Anti-Cheat or EA App service instability
Both FC 26 and BF6 use the same EA Anti-Cheat system.
When that service fails mid-session, it force-closes the game instantly with no crash dialog.
EA App runtime / authentication token error--
Sometimes the EA App loses its background connection to your account while a game is running, causing an instant return to desktop.
DirectX or Frostbite shared runtime issue
EA titles use shared DirectX components and Visual C++ libraries. If those are corrupted or mismatched, it can crash multiple EA games the same way.
- Edit - Because both EA games crash the same way while all your other games run fine, this is almost certainly an EA Anti-Cheat or EA App runtime problem, not your hardware or Windows setup. I'm not 100% sure on fixing it but if you cant, gather your Windows Event Viewer logs (look for “Faulting module EAAntiCheat.GameService” or “EAApp.exe”) something like that and submit them to EA Help that’s what EA support will need to escalate the issue.
