First you have to go into thin location (or where you installed the game):
Local Disk (C) – Program Files (x86) – Origin Games – FIFA 23 – _Installer – EAAntiCheat
Open EaAntiCheat.Installer file, select FIFA 23 from the drop-down and then click uninstall
After that Restart your computer and Run the Game as Administrator
