Game won't launch: EC:10502 + "You don't have access", only my own PC

Hi,

I’m getting two alternating errors when trying to launch my game:

1. Something went wrong

You've launched this game on too many devices in the last 24 hours. Wait a bit before relaunching on this device. Error code: EC:10502

1. You don’t have access

This title may have been downloaded to your device by another user who owns the game. Log in to a different account or restart the app to try again.

What I have checked & tried：

• Checked my EA account security page, only my PC EA App and EA web page are listed as logged‑in devices. No other unknown devices.
• I have revoked / removed all trusted devices from account settings.
• Restarted EA App, repaired game files, rebooted PC, cleared EA App cache.
• Still cannot launch the game, the two errors keep popping up alternately.

There is no second computer or shared account. My account is only used by myself. Is there any fix for EC:10502 besides waiting a full 24‑hour cooldown? Please help.😭
