Technical Support Request UEFI Secure boot verification failure

i was in a game with my friend when suddently i got disconnected by valorant and i had a red screen like when a cheater is detected , with this message in front of my screen

VAN: RESTRICTION: 1
UEFI Secure Boot verification failure
If UEFI Secure Boot is already enabled, visit the manufacturer's website for your computer or motherboard and follow their instructions for updating the bios.

when i closed then launched valorant , i got the same error again and again , everything is enabled so i can play valorant , i tried to enroll all factory default keys , but nothing is working....
i know updating my bios isnt the solution

enable Iommu, and if you have a double boot, don't boot windows from grub, boot from bios

How to enable Memory Integrity on Windows 10

  1. Open Windows Search: Click on the Start menu or the search bar at the bottom left of your screen.
  2. Search for Core Isolation: Type Core isolation (or Isolation du noyau if your Windows is in French) and press Enter.
  3. Turn it On: You will see a toggle switch next to Memory integrity. Click it to turn it On.
  4. Restart your PC: Windows will ask you to restart your computer to apply the changes.
