My pc doesn't startup when vanguard is installed

Technical Support Request

Hello, I'm having a problem with the Vanguard anti-cheat.
Every time I install it, my computer won't turn on and the boot cycles endlessly. I restart my pc it turns on but league doesn't work and it shows me VAN 57 Error.
I've already tried:

enable VGC in config

reinstall

I have secure boot enabled/UEFI and the BIOS updated

Windows 11
