Hi everyone,

I'm having a massive headache trying to open VALORANT after the latest update, and nothing seems to fix it. I’ve tried every major troubleshooting step found online, but the anti-cheat is completely stuck.

Here is the full timeline of the issue:

1. The Trigger: Right after the game updated, I started getting the dreaded "VAN: RESTRICTION: 1 (UEFI Secure Boot verification failure)" error.
2. The BIOS Fix: I have a Gigabyte GA-A320M-S2H motherboard. I went into the BIOS, disabled CSM Support, switched Secure Boot to Custom, restored the Factory Keys, switched back to Standard, and successfully enabled Secure Boot.
3. The Current State: Windows 10/11 now recognizes Secure Boot as Enabled/Active. TPM 2.0 is also active and verified.
4. The New Problem: Even with Secure Boot fully working, the game still won't launch. When checking Windows Services (services.msc), I noticed the vgc service was set to Manual.
5. The Error: Every time I try to switch vgc to Automatic and start it manually, Windows blocks it and triggers: "Error 1: Incorrect function".

What I have tried so far:

• Setting both vgtray.exe and vgc.exe to Run as Administrator.
• Completely uninstalling Riot Vanguard, restarting the PC, and letting the Riot Client reinstall it.
• Double-checking msinfo32 to confirm Secure Boot is genuinely active (it is).

Has anyone faced this exact loop where Secure Boot is fixed but the vgc service completely breaks with Error 1 after the latest patch? Any help or workarounds would be highly appreciated.

Thanks!
