EA FC 24 Account Login Error

My EA FC 24 gameplay experience has been hampered by a constant login issue for the past few days. The game would refuse to launch unless repaired, leading me to suspect a computer problem. I chose to execute a system format in the hopes of resolving the underlying issue. However, following the format, the game runs successfully, but I can't access my previously saved accounts. I've tried reinstalling the game, making repairs, and even deleting and rebuilding my account, but the problem still exists. If anyone has faced this problem and discovered a solution, please share your findings.
