Complete guide to troubleshoot Valorant Error 138 with advanced solutions and prevention strategies
Understanding Valorant Error 138
Valorant has achieved remarkable popularity within the gaming community since its initial announcement and subsequent beta testing phases. The tactical shooter rapidly gained widespread recognition during its early development stages, prompting Riot Games to deploy global versions following extensive testing periods. As with any newly developed gaming platform built from the ground up, certain technical aspects may require additional refinement. This developmental reality occasionally manifests as Valorant Error Code 138, a security-related issue that can disrupt gameplay sessions. Fortunately, comprehensive troubleshooting methods exist to resolve this concern effectively while enhancing your overall gaming experience.
Common triggers for Error 138 include: outdated graphics drivers, conflicting background applications, corrupted Vanguard installations, and restrictive Windows security policies. Many players encounter this error after major system updates or when installing new security software that interferes with Valorant’s anti-cheat protection layer.
Vanguard Anti-Cheat System Solutions
Riot Vanguard serves as the proprietary anti-cheat solution specifically engineered for Valorant’s security infrastructure. This kernel-level protection system requires specific system permissions to function correctly. When Error 138 appears, the initial troubleshooting step involves completely removing and reinstalling the Vanguard software to eliminate potential corruption or version conflicts.
Navigate to the Programs and Features section within your Windows Control Panel interface. Locate the Riot Vanguard entry in the installed applications list, then right-click and select Uninstall. Following complete removal, perform a full system restart to clear any residual components from memory before reinstalling the software through the official Valorant client.
Advanced Vanguard Management Tip: For persistent Error 138 occurrences, consider temporarily disabling other security software during gameplay sessions. Antivirus programs and system optimization tools sometimes falsely flag Vanguard’s legitimate activities as suspicious behavior, creating conflicts that trigger error codes.
Advanced System-Level Fixes
Administrative command line interventions can resolve underlying Windows security configuration issues that contribute to Error 138. Launch Command Prompt with administrator privileges and execute the following sequential commands:
Important Note: If the system returns “The value is protected by Secure Boot policy and cannot be modified or deleted” error message, access your motherboard’s BIOS/UEFI interface during system startup and disable the Secure Boot option. After saving BIOS changes and rebooting, reattempt the command sequence for complete resolution.
BIOS Navigation Strategy: Secure Boot settings typically reside under the Security, Boot, or Authentication tabs within your BIOS interface. The exact location varies by motherboard manufacturer, so consult your system documentation if uncertain. Remember to re-enable Secure Boot after resolving Valorant issues if you require this security feature for other purposes.
Process Management and Compatibility Settings
Optimizing how Valorant and Vanguard interact with your operating system can prevent Error 138 recurrences. Begin by accessing the Task Manager using the Ctrl + Shift + Esc keyboard shortcut combination. Within the processes tab, locate the Vanguard tray notification entry specifically.
Additionally, configure Valorant’s compatibility settings for optimal performance. Right-click the Valorant desktop shortcut icon and access Properties, then navigate to the Compatibility tab section. Enable “Run this program in compatibility mode” and select Windows 8 compatibility for most systems, as this often resolves version conflicts.
Priority Setting Insight: Setting Vanguard to Normal priority prevents resource conflicts with other critical system processes while maintaining necessary anti-cheat functionality. Avoid setting it to High or Realtime as this can cause system instability during intensive gaming sessions.
Proactive Prevention Strategies
Implementing regular maintenance routines significantly reduces Error 138 frequency and enhances overall gaming stability. Schedule monthly graphics driver updates through NVIDIA GeForce Experience, AMD Adrenalin, or your GPU manufacturer’s official utility. Outdated display drivers represent a common but often overlooked trigger for Valorant errors.
Perform clean Vanguard reinstalls following major Windows updates, as system-level security changes can disrupt existing anti-cheat configurations. Monitor background applications for potential conflicts—recording software, performance monitors, and RGB lighting controllers sometimes interfere with Vanguard’s operation.
