Because cracked files modify the game's binary, Windows Defender or third-party antivirus often blocks their network access.
Note: The effectiveness of these fixes depends entirely on which specific "release" or "repack" of the game you have installed.
Note: These workarounds are not guaranteed and may introduce malware. Many crack sites bundle viruses with “fixes.”

Before fixing the problem, you need to understand its origin. In legitimate copies of Black Ops 3, the game connects to Call of Duty’s servers to load "live" menu content: featured playlists, seasonal events, daily challenges, and store updates. When the game client cannot fetch this data—or fetches corrupted data—it generates a UI error with a specific code.
For cracked versions, the situation is worse. The crack usually emulates a server response or disables online checks. However, many repacks (from groups like RG Mechanics, FitGirl, or CorePack) include outdated DLC unlockers or partial emulators. UI Error 27393 specifically means:
In short: the game is looking for something that isn’t there, and the crack isn’t smart enough to skip it.
DRM solutions like Denuvo function by obfuscating the game's critical code sections. They utilize virtualization and encryption, meaning the game code is decrypted dynamically during runtime. In short: the game is looking for something
