Fix PUBG Error 25: BattlEye Corrupted Data (Client Not Responding) (2025)

Updated: 11/29/2025

You launch PUBG, the logo appears, and then a popup throws you out with Error 25, BattlEye Corrupted Data or a message saying the client will close because the anti cheat is not running correctly. The game either never reaches the lobby or crashes a few seconds after you join a match. This usually means BattlEye or some of your game files are damaged, blocked, or out of sync after an update or system change, not that your PC suddenly became too weak to run PUBG [web:123][web:124][web:125][web:130][web:139].

Method 1: Verify And Repair PUBG Game Files

Going forward, let large PUBG patches and BattlEye updates complete without forcing the launcher to close or shutting down your PC mid install. Many players report that error 25 first appeared right after an update that was interrupted or stalled, which left anti cheat data in a half written state [web:123][web:130][web:139].

Method 2: Reinstall Or Repair BattlEye Anti Cheat

Some antivirus suites or aggressive security tools can interfere with anti cheat drivers and make BattlEye think its own files are compromised, leading straight to Error 25. Temporarily pause real time protection and game mode features in your antivirus, then launch PUBG to test, if the error goes away, add PUBG and BattlEye folders to your antivirus exclusion list before re enabling protection [web:123][web:125][web:133].

Warning: Only download PUBG and BattlEye from official stores, do not trust third party patches or cracked anti cheat files, which can trigger bans and additional errors on top of Error 25 [web:125][web:139].

Method 3: Reset Background Services And Check For Conflicts

If every fix above fails and Error 25 appears instantly on launch, uninstall PUBG completely from your launcher, manually delete any leftover PUBG and BattlEye folders, then reinstall the game to a different drive if possible. Official support notes that a full reinstall is the definitive fix when deeply corrupted anti cheat data keeps returning after partial repairs [web:123][web:130][web:139].
