Windows 10: BSOD From Valorant vgk.sys please help

Hi, I've had some issues regarding Riot game's Vanguard "Vgk. sys" DLL file in which the BSOD presents itself with the Stop code "DRIVER_VERIFIER_DETECTED_VIOLATION" and ONLY that stop code. I've tried things such as giving Valorant Administrator perms or adding some files into exception for the firewall while trying to solve a different problem but can't seem to understand what keeps causing the blue screens for this. For context I was playing the game with No issue present about two months ago when I took a break and when I came back to update the game I started getting all of these issues I

Hi, thanks for reaching out. My name is Bernard a Windows fan like you. I'll be happy to help you out today.

I understand the issue you have, there is nothing to worry I am here to help, as per checking and analyzing the DMP files you have, there is an error vgk.sys, this is the Vanguard kernel-mode driver or the Vanguard driver from Riot games, if you have games like Valorant I suggest reinstalling it and check again if the issue persists, kindly follow the steps from this link:

BSOD when closing valorant

Just for information in case others see it as the cause, it's not the process that caused the exception, the process is shown because in that process the exception was raised. Because in a process a lot of stuff can happen (e.g. networking, I/O operations, ....), the process itself should not be considered as the cause. If you check the call stack, it shows that a driver, vgk, makes a call to free pool. Code:

Looking specifically at the instruction where the problem occurred, unless my memory is off and the relevant register's value is not saved during a crash, this looks to be subtracting (rsi address - 0Dh) with an address not pointing to anything which isn't possible. Because of the IRQL in parameter 2 of the bugcheck in combination with this operation the crash occurs. Code:

The vgk driver looks to be from the anticheat software used by Valorant. Definitely contact Valorant support about this.
