Consistent BSOD - Riot Vanguard - How to prevent / fix ongoing issue?
*PLEASE NOTE* I was confused by the select a product requirement for this question. I am unsure if this is the right place to ask as Windows 11 was not an option. Please redirect or advise how and where to post if this is not the right place
Roughly a week ago I started experiencing the Blue Screen of Death. Unable to source the issue via event viewer, I referred to the Minidump files the crashes were creating.
Using WinDbg, I was able to find that vgk.sys is the driver causing the failure. I am unfamiliar with how to read the analysis and see what is causing the driver to fail, and there is very little online regarding this issue.
The crashes are consistent with Riot Vanguard, the anti-cheat software used by Riot for it's games League of Legends and Valorant.
Crash times are inconsistent. I've crashed at:
System Startup
Launching Riot Client
Accepting League of Legends game queues.
I've also crashed without ever launching the Riot Client, but noticed Vanguard is a mandatory start-up application. Crashes happen seconds, minutes or hours after startup or interaction with League of Legends or the Riot Client.
I've tried the following:
Updating Windows
Updating graphics drivers
Updating audio drivers
Running Windows Defender quick and full system scans
Utilized the repair tool to find any corrupted windows files
Uninstalled and reinstalled Riot Vanguard
Uninstalled and reinstalled League of Legends
Uninstalled and reinstalled both above applications at the same time
Ran Riot Client as Administrator
I have not tried reinstalling Windows. That is my last resort and I'm unsure if that would fix the problem anyway.
Here is a link to the minidump files. I've zipped them. https://drive.google.com/file/d/1Aw1bc0lBH0BHoGgNcPb6cJbJK5o85XF2/view?usp=sharing
