This error typically indicates a problem with Valorant’s Vanguard anti-cheat system, specifically relating to its initialization or a conflict with other software. This guide will walk you through the common causes and provide a comprehensive set of fixes to resolve the issue.

🧐 Causes

• Driver Conflicts: Incompatible or outdated drivers, particularly graphics drivers, can interfere with Vanguard.
• Software Conflicts: Certain software, especially security programs (antivirus, firewalls), or hardware/virtualization software can clash with Vanguard.
• Corrupted Vanguard Files: The Vanguard installation files themselves might be damaged or incomplete.
• Administrator Privileges: Valorant and Vanguard require administrator privileges to function correctly.
• System File Corruption: Rarely, corrupted system files can contribute to the error.

🔧 Fixes
