The same issue has been posted as a technical issue, but I'm reposting it as a bug because it's so fatal that the game can't be started.

We suspect a server-side problem or data inconsistency, so please check it out!

Also, if anyone has the same problem, please help!

### Situation

- When left-clicking in the main menu to go to the lobby, after transitioning to the loading screen, the error "Disconnected: Detected Data Mismatch" appears and returns to the main menu.

### Conditions

- Logged in for the first time after a break of 1-2 years

### Tried

- Reinstall the game

- Re-login

- Change launcher

  - Origin

  - EA App

  - Steam

- Ask my friend to log in from the problematic PC with his account (he was able to log in from the PC)

- Check internet connection

- Review/disable firewall settings

- Delete all temporary files under User/AppData/

  - All EA folders

  - All Origin folders

  - All Steam folders

- Disabling Cloud Sync

  - Steam

  - EA App(By blocking EALocalHostSvc.exe on firewall)

- Regenerating config.cfg under Users/UserName/Saved Games/Respawn/ by deleting the directory

Please let me know if there is anything else I can try.
