If you play Valorant on Windows 11, you may have run into a frustrating message that prevents the game from launching properly or causes sudden crashes mid-match. Many players report that after a system update or security change, Valorant refuses to start and throws a VAN error related to HVCI. This issue can be confusing because it is not caused by hardware failure or corrupted game files, but by a Windows security feature that conflicts with Riot Vanguard. Understanding why the HVCI enabled VAN error appears in Valorant is the first step toward fixing it without breaking system stability.

Part 1: What Is an “HVCI Enabled” VAN Error in Valorant & Why Does It Appear?

The “HVCI enabled” VAN error in Valorant is triggered when Windows 11’s Hypervisor-Protected Code Integrity conflicts with Riot Vanguard, Valorant’s anti-cheat system. HVCI is designed to protect your system by isolating critical processes, but Vanguard requires low-level access to function correctly. When both try to control the same system layer, Valorant may crash, fail to launch, or display a VAN error.

Common reasons this error appears include:

• HVCI being automatically enabled after a Windows 11 update
• Incompatible drivers running under memory integrity protection
• Conflicts between Riot Vanguard and Windows virtualization features
• BIOS virtualization settings interfering with Vanguard
• System security policies blocking Vanguard’s kernel-level access

This is why many players describe the problem as HVCI making their PC crash Valorant, even when their hardware meets all requirements.

Solution 2: Disable Memory Integrity (HVCI) in Windows Security

Disabling HVCI is the most commonly suggested fix, but it lowers system protection.

Step 1. Open Windows Security

Step 2. Go to Device Security

Step 3. Click Core Isolation details

Step 4. Turn off Memory Integrity

Step 5. Restart your PC

Solution 3: Disable Virtualization-Based Security via Group Policy

Some players attempt to turn off virtualization features entirely.

Step 1. Press Win + R and type gpedit.msc

Step 2. Navigate to Device Guard settings

Step 3. Disable Virtualization-Based Security

Step 4. Apply changes and restart

Step 5. Relaunch Valorant

Solution 4: Update or Roll Back Problematic Drivers

Outdated or incompatible drivers can trigger HVCI conflicts.

Step 1. Open Device Manager

Step 2. Check for drivers marked as incompatible

Step 3. Update or roll back those drivers

Step 4. Reboot your system

Step 5. Test Valorant again

Solution 5: Modify BIOS Virtualization Settings

Some players try to resolve the issue at the firmware level.

Step 1. Restart and enter BIOS

Step 2. Locate CPU virtualization settings

Step 3. Disable virtualization support

Step 4. Save changes and reboot

Step 5. Launch Valorant

Solution 6: Reinstall Riot Vanguard Completely

In some cases, the HVCI enabled VAN error in Valorant is caused by a corrupted or outdated Riot Vanguard installation that no longer aligns with current Windows 11 security settings. A clean reinstallation can sometimes reset the conflict, although it does not prevent HVCI-related issues from returning after system updates.

Step 1. Close Valorant and exit Riot Client completely

Step 2. Open Control Panel and uninstall Riot Vanguard

Step 3. Restart your PC to fully remove Vanguard services

Step 4. Launch Valorant to trigger automatic Vanguard reinstallation

Step 5. Restart again and test if the VAN error is resolved

Conclusion

The HVCI enabled VAN error in Valorant on Windows 11 is not a simple bug, but a conflict between modern Windows security architecture and Riot Vanguard’s anti-cheat system. While disabling HVCI or changing system settings can temporarily fix the issue, these solutions often introduce new risks or stop working after updates. For players who want a safer, long-term solution, LagoFast offers a smarter approach by resolving conflicts without compromising system security. If HVCI is making your PC crash Valorant or preventing the game from launching, choosing a dedicated game booster is the most stable way to get back into competitive play without frustration.
