Final answer:
To fix the issue where Vanguard blocks a file from loading, update all drivers, perform a clean boot, reinstall Vanguard, and check for conflicting software. If the problem persists, contact Riot Games' support.
Step-by-step explanation:
The message 'Vanguard has blocked the following file from loading on your system: /device/harddiskvolume3/windows/system32/drivers/' indicates that there is a driver or service on your computer that Riot Games' anti-cheat software, Vanguard, has deemed suspicious or incompatible with Valorant. To fix this issue, you can try the following steps:
- Update all drivers to the latest versions, especially those related to your graphics card and other critical system components.
- Perform a clean boot to verify if any third-party software is causing the conflict.
- Reinstall Vanguard by fully uninstalling it and then running Valorant again to prompt a fresh installation of the anti-cheat software.
- If the error persists, check for any software that could be conflicting with Vanguard and consider removing or updating it.
If none of these steps resolve the issue, it may be necessary to seek further assistance through Riot Games' official support channels.
