# KMODE_EXCEPTION_NOT_HANDLED

If you encounter a Blue Screen of Death (BSOD) or crash with the stop code **KMODE\_EXCEPTION\_NOT\_HANDLED (0x1E)**, it means a kernel-level conflict is preventing the cheat's driver from loading.

## Common Cause: Outdated Version

Before changing your system settings, you must verify the status of the cheat.

<Warning>
  **Is the cheat updated?**

  A common cause for this crash is attempting to inject a cheat that is **outdated**.

  Please check the `#announcements` channel in our Discord. If the cheat is currently marked as **UPDATING**, this crash is expected behavior. **Do not** attempt to inject until a new update is released.
</Warning>

## Cause

<Warning>
  **Virtualization Interference**

  This error is caused by Windows **Virtualization-Based Security (VBS)** or **Memory Integrity**.
  To run the cheat, you must disable these protections so the loader can inject properly.
</Warning>

## Solution

To resolve this, you must disable virtualization-based security features in both Windows and your BIOS.

<Steps>
  <Step title="Disable Core Isolation (Windows)">
    1. Open your Windows Start Menu and search for **"Core Isolation"**.
    2. Click on the system setting result (it may also be listed under **Device Security**).
    3. Find the toggle for **Memory Integrity** and turn it **OFF**.
    4. Restart your computer if prompted.
  </Step>

  <Step title="Disable Virtualization (BIOS)">
    You must enter your BIOS to disable hardware virtualization.

    1. Restart your PC and spam your BIOS key (usually `DEL`, `F2`, or `F10`).
    2. Navigate to **CPU Configuration** or **Advanced** settings.
    3. Find the virtualization setting and set it to **Disabled**.

    <Note>
      **Common BIOS Names:**

      * **Intel:** Intel Virtualization Technology, VT-x, VT-d
      * **AMD:** SVM Mode, AMD-V
    </Note>
  </Step>
</Steps>

<Note>
  After disabling these settings, ensure you **Restart your PC** completely before attempting to inject the cheat again.
</Note>
