Battle.net's Scan and Repair getting stuck in a loop prevents playing Call of Duty, World of Warcraft, Overwatch 2, Diablo, and other Blizzard games.
How to fix it:
- Delete the Battle.net cache: close the app completely (check Task Manager), delete %PROGRAMDATA%\Battle.net\Agent and %APPDATA%\Battle.net
- Add the game folder AND Battle.net folder to your antivirus exclusions — antivirus commonly blocks the repair process
- Make sure you have at least 30GB free on the game's drive — repair needs extraction space
- Delete the game's 'indices' folder in its installation directory — this forces a proper re-scan
- Run Battle.net as Administrator
- Check disk health with CrystalDiskInfo — failing drives cause persistent file corruption
- If nothing works, uninstall the game (saves are in the cloud for most Blizzard games), delete the game folder manually, then reinstall
- Reinstall Battle.net launcher itself — download fresh from battle.net
