How to fix Error 559 on Windows 11

Why This Error Happens

Error 559 occurs when the Windows exception-handling mechanism attempts to walk the call stack (an “unwind” operation) during structured exception handling (SEH) but finds that the function table—metadata describing stack frame layout for a given code region—is corrupted or improperly formed. This typically happens due to a corrupted or mismatched DLL/EXE file (often after an incomplete update or bad third-party patch), memory corruption caused by a faulty driver, or a security/AV tool injecting hooks into a process without properly registering the corresponding unwind data. Since x64 Windows relies on accurate function tables for exception propagation, any inconsistency here causes the OS to abort the unwind and throw this error.

Step-by-Step Resolution Guide

  1. Run System File Checker and DISM to repair corrupted OS binaries:
  • Open Terminal (Admin) and run:

    sfc /scannow
    DISM /Online /Cleanup-Image /RestoreHealth
  • Restart the PC after completion.
  1. Identify the faulting module using Event Viewer:
  • Go to Event Viewer > Windows Logs > Application.
  • Locate the Error 559 event, note the associated .dll or .exe file and its file path.
  • If it’s a third-party application file, reinstall or repair that application via Settings > Apps > Installed Apps.
  1. Update or roll back device drivers, especially GPU, chipset, or antivirus/security drivers, since faulty low-level hooks are a common cause:
  • Open Device Manager, right-click the suspect device, select Update driver.
  • If the issue began after a recent driver update, choose Roll Back Driver instead (Properties > Driver tab).

  1. Temporarily disable third-party antivirus/EDR software that performs API hooking (common with some security suites) and test if the error persists. If resolved, update the security software to the latest version or exclude the affected process.

  2. Check for pending Windows Updates under Settings > Windows Update, as Microsoft periodically patches SEH/unwind-related bugs in the kernel and C runtime libraries. Install all pending updates and reboot.

Alternative or Verification Steps

  • After applying fixes, reproduce the original action that triggered Error 559 and confirm no new event is logged in Event Viewer under Application or System logs.
  • If the error persists only in one specific application, use Process Monitor (Sysinternals) to trace the exact module loaded at the time of the crash, then perform a clean reinstall of that specific application or its runtime (e.g., Visual C++ Redistributables).
