SPECIAL POOL DETECTED MEMORY CORRUPTION when playing Valorant

Hello Raihan, I'm Quinn, and I'm happy to help you.

The SPECIAL_POOL_DETECTED_MEMORY_CORRUPTION (c1) bugcheck you’re encountering is indicative of memory corruption detected by the Special Pool mechanism. This often points to a driver issue or some problem with how the system is handling memory allocation and deallocation.

From the analysis, the key details are:

Bugcheck Code: c1
Faulting Driver: vgk.sys
Module Name: vgk

The driver responsible for the crash is "vgk.sys", which is associated with the Riot Vanguard anti-cheat system used by Valorant. This suggests that the issue might be related to the Vanguard driver itself.

Make sure that Riot Vanguard is up-to-date. Riot Games frequently releases updates that might include fixes for stability issues. You can usually update Vanguard by updating Valorant or manually through its settings. If it does not work, you can try to Uninstall Riot Vanguard and Valorant, and then reinstall both. This can sometimes resolve issues related to corrupted or outdated drivers.

If the problem continues, please don't hesitate to ask for further assistance. I'm here to help in any way I can.

I tried clean reinstalling both vanguard and valorant and the issue still presist

here's the dumpfile:

The dump file analysis indicates that the 'vgk.sys' driver, a component of Riot's Vanguard anti-cheat system, is the root of the problem. This kind of memory corruption is typically a sign of a driver bug or incompatibility with other software or hardware. Since you've already tried reinstalling Vanguard and Valorant, let's try to Deactivate Memory Integrity. Windows 10 and 11's Memory Integrity feature (under Core Isolation) can conflict with specific drivers. To disable it, navigate to Windows Security > Device Security > Core Isolation Details and toggle off Memory Integrity. Reboot your computer and check if the problem is resolved. Feel free to reply if you need further assistance.

Memory Integrity is off when i sent that dumpfile

My apologies if that didn't work already. Let's try updating your drivers. Updating your graphics, network, and storage drivers, as well as your system BIOS/UEFI firmware and Windows, could fix the memory corruption error.
