I, like many other players, have got an error (VAN-6) that disconnected me in the middle of every match i played. I made a ticket and they couldn't fix it blah blah blah. I have tried everything there is on the internet that says I could fix the error, but it only helped temporarily.

And now I believe I may have found a fix for this, by mistake. I had to reset my pc because it was too sluggish, i didn't even uninstall Valorant (because i didn't install it in C:, so it didn't get wiped out with the fresh Windows install) and I played my matches like usual, and guess what? No disconnections. I might just be lucky, or a coincidence. But i think it's worth trying.

Now, I was thinking what might have changed with this reset so that the game would fix itself, and i still might be wrong, but it's just my thought: When the game launched in may, there was a Vanguard bug in which it would block your mouse and/or keyboard and/or other RGB drivers from your PC, thinking it was suspicious. At that time, the only good fix i found was this: https://www.youtube.com/watch?v=j5_x8FfBQVQ
In this fix you change some text that you shouldn't usually change, or idk, the idea is that i believe that that problem (Vanguard blocking the mouse/kb) was fixed by Riot later on, and then Vanguard would see that text file as being malicious. After all, i was told by Riot support that VAN-6 is a hardware ban kind of error, and it would make sense.

TL;DR: If you got the VAN-6 error, you might want to try and reset your PC.
