VAN9003 error pls help

I need help I previously had a VAN9003 error I looked for a tutorial on youtube, opened bios and made sure 'secure boot' is 'enabled' and 'bios mode' shows 'UEFI'. But I tried to open valorant twice now and restarted a bunch of times but it keeps getting stuck on loading screen... The pc I'm using is brand new idk if I need to change anything else because I am clueless about this stuff..
