The Easy Anti-Cheat (EAC) tool may detect a local file integrity violation in Sea of Thieves, indicating a potential game file modification. To resolve this, verify the game files through Steam or the Xbox app to restore the original files and ensure game integrity.

If file verification fails, consider disabling antivirus or firewall software that may be interfering with EAC. Exception rules can be added to allow EAC full access, preventing further file integrity violations. Additionally, reinstalling the game can resolve file corruption issues and restore game functionality.
