Game Startup Error

Hello, I cannot launch EA SPORTS FC 25 via Steam/EA App. Error shown: “Failed to launch game – An error on our end caused the launch to fail.” EA App also says: “Some features have been disabled because the EA App launched from another application.”

I already tried: reinstalling both EA App and the game, clearing EA cache, verifying files in Steam (3 files were reacquired), running both apps as admin, repairing game, closing EA Background Service, checking firewall/antivirus. Nothing worked.

It seems to be an account/Steam–EA link issue. Does anyone have a solution???
