This is one of the most common errors when starting the loader. It is caused by Windows blocking vulnerable drivers at the system level.
Step-by-step solution
- Disable Windows Defender and Smart Screen in your security settings.
- Turn off Core Isolation in Device Security settings.
- Completely uninstall any third-party antivirus software and Faceit Anti-Cheat if installed.
- Use the Vulnerable Driver Disabler utility to disable the driver blocklist.
