How to Fix: KMODE_EXCEPTION_NOT_HANDLED (0x1E) while playing Dune: Awakening

Are you experiencing a Blue Screen of Death (BSOD) specifically while playing Dune: Awakening? The most common error codes for this issue are 0x1E (KMODE_EXCEPTION_NOT_HANDLED) or 0x3B (SYSTEM_SERVICE_EXCEPTION), often pointing to NETIO.SYS.

This crash is frequently seen on Windows 11 Insider Builds (e.g., Build 26200). Here is why it happens and how to fix it.

1. Why does it happen during Dune: Awakening?

Dune: Awakening is a high-performance Unreal Engine 5 game. As an MMO, it creates massive network traffic and heavily utilizes the system’s kernel for anti-cheat and data processing.

On Windows Insider builds, third-party security software (like ESET, Bitdefender, or Avast) often fails to handle these network requests correctly, leading to an “Access Violation” (0xC0000005) in the Windows network stack (NETIO.SYS).

2. The Solution: Step-by-Step

Step A: Remove Third-Party Antivirus (The “Dune” Fix)

In our testing, the primary cause of this crash is a conflict between the game’s network activity and third-party firewall/antivirus filters.

1. Uninstall your antivirus (e.g., ESET) via the Apps & Features menu.
2. Use the official Removal Tool: To completely clear the kernel filters, you must use the manufacturer’s cleanup tool (like the ESET Uninstaller Tool). Standard uninstallation often leaves “ghost” drivers behind that continue to cause crashes.
3. Rely on Windows Defender: For Windows Insider builds, Windows Defender is the most stable option as it is natively updated to work with experimental kernel changes.

Step B: Identify Active Network Filters

To verify that no leftover drivers are still interfering with your game:

1. Right-click the Start button and open Terminal (Admin).
2. Type fltmc filters and press Enter.
3. If you still see names like eamonm or edevmonm, driver remnants are still active and must be removed using the manufacturer’s specialized cleanup tool in Safe Mode.

Step C: Fix System Corruption

Repeated Blue Screens can corrupt your game and system files. Run these commands in an Admin Terminal:

• sfc /scannow
• Dism /Online /Cleanup-Image /RestoreHealth

3. Hardware Stability Check

Since Dune: Awakening uses Unreal Engine 5, it pushes your RAM and CPU to their limits.

• RAM Overclocking: If you have XMP or EXPO enabled in your BIOS, try disabling it. Windows Insider builds are less stable with aggressive memory timings, which can trigger the 0xC0000005 error during high-load gaming.
• Update Drivers: Ensure your Chipset and Network (LAN/Wi-Fi) drivers are updated directly from your motherboard manufacturer’s website, not just through Windows Update.

Summary for Gamers

If you are playing Dune: Awakening on a Windows Insider Build, the best way to ensure stability is to uninstall third-party antivirus suites and use Windows Defender. This prevents “Access Violations” in the network stack while the game handles high volumes of server data.
