Verify Fortnite files, run the Easy Anti-Cheat repair included with Fortnite, restart Windows, and check that security software is not blocking the signed Epic/EAC service.
Review Windows Security or installed antivirus history for a blocked signed Epic or Easy Anti-Cheat file. Restore or allow only when the file path and publisher match Epic’s guidance.

Remove unsupported modifications
Close injectors, debuggers, overlays, and unsupported modifications. Do not disable kernel protections or download replacement anti-cheat files.

Escalate the exact code
If repair and verification fail, send Epic the EAC code, Fortnite build, Windows version, security-product name, and repair result.

If it does not work
If Verify restores files but the same EAC code returns, run Repair Service from the Easy Anti-Cheat setup bundled inside Fortnite and restart Windows before retesting.
If security software quarantined an EAC file, restore or allow it only when the path and signed publisher match Epic’s installation; never download a replacement service or DLL.
