Error code VAN9005 indicates configuration issues with Secure Boot, TPM, or your Windows version. Follow these steps to resolve it:
1. Secure Boot / TPM Configuration:
- Check and ensure Secure Boot and TPM are enabled in your BIOS settings. If your system is using Legacy BIOS (MBR) mode instead of UEFI, enabling Secure Boot can render your OS unbootable. To avoid this, convert your drive to GPT and switch from Legacy BIOS to UEFI mode first.
- For detailed instructions, refer to the support article: Addressing Virtualization-based security (VBS) settings on Windows 10
2. Update Windows:
- Ensure your Windows OS is up-to-date. Go to Settings > Update & Security > Windows Update, and check for updates.
After ensuring Secure Boot/TPM is enabled and your OS is updated, restart your PC and try launching VALORANT again.
