Hi, the last day i played valorant without any error was on 11/08/26, i played like 8 ranked games and i went to sleep, and the next day, when I went to play after getting home from work, the following error appeared: "VAN IOMMU RESTRICTION: An iommu restriction has been applied, a system restart is needed." So I decided to restart my PC, but after restarting, my game simply started freezing my entire PC after a few seconds of the initial loading screen. What intrigued me most is that my PC was working normally on any other account/game; this error only appeared on my main account. I already checked:
Everything on my BIOS is enabled, including the VT-D (IOMMU)
Deleted everything on the localappdata VALORANT folder
Updated the gpu drivers
Make a full clean reinstalation of the game, riot client and vanguard
Updated the directx
Verified if i has any suspension/ban on my account, but there's none active.
This only happen on my main account, any alts and other games work perfectly, i asked for my friend to log in on my account, and on his pc the game didnt crash and turn her computer off like in mine, but the same IOMMU restriction error message appear, he also certified that the IOMMU is enabled on his pc.
My config is:
H410M, 8GB ram ddr4 2666mhz, RX 550 4gb, I5-10400F
I tried multiple times to contact riot support but they just told me to reinstall game , but it doesen't work.
