This means some antivirus or anti-cheat service is still running. Review the "Before Running the Tool" section and make sure all antivirus software is completely removed and all anti-cheat services are disabled.
If you are sure that you did everything correctly but still getting a blue screen, you need to do a clean install of Windows 10 or 11 with latest updates, install C++ libraries from this guide and GPU drivers (without any motherboard or other drivers), then try to use the tool again.
