The constant HVCI (Hypervisor-protected Code Integrity) error in Valorant usually relates to issues with your system's security and virtualization settings. Valorant's anti-cheat software, Vanguard, uses HVCI to enforce strict security measures, and any inconsistency in these settings can trigger this error.
Here are a few common steps that might help you resolve this issue:
1. Disable Virtualization-based Security (VBS): If your system isn’t fully compatible with HVCI, VBS might cause issues. You can disable VBS by running the command `bcdedit /set hypervisorlaunchtype off` in an elevated command prompt, then restart your PC.
2. Check for UEFI and TPM 2.0 Support: If your system supports UEFI and TPM 2.0, ensure they are both enabled. Otherwise, Valorant might prompt errors like HVCI or prevent the game from launching.
3. Verify Core Isolation Settings: Make sure that core isolation is properly configured under Windows Security settings. Some users report issues with enabling this feature due to compatibility reasons.
4. Consider Updating Your BIOS/UEFI Firmware: Sometimes, outdated firmware can cause conflicts with newer security features like HVCI. Updating it might help resolve these errors.
Try these steps, and if the issue persists, additional troubleshooting or reconfiguring your BIOS settings may be necessary.
