Here is a detailed guide on resolving the VAN 9003 error on Windows 11:

Step 1) Review BIOS setting

Initiate the process by restarting your PC and accessing BIOS settings using keys like F1 to F12, Delete, or similar, depending on your system. Once done, verify that your BIOS is set to UEFI mode and disable CSM (Compatibility Support Module) if it's active.

Step 2) Activate Secure Boot

Locate the Secure Boot option within BIOS settings and ensure it's enabled. Note that enabling Secure Boot may affect dual-boot setups but can be adjusted later if required.

Step 3) Enable TPM (Trusted Platform Module)

Search for TPM settings in BIOS and enable them. Opt for TPM version 2 if available, and confirm that firmware TPM is activated.

Step 4) Save changes and reboot

After making these adjustments, save settings in BIOS and reboot your system.

Step 5) Validate Configuration changes

Post-reboot, recheck BIOS settings to ensure UEFI mode, Secure Boot, and TPM are all active as needed.

Step 6) Test the game

Launch Valorant and log in to confirm if the "VAN 9003" error has been resolved. You should now be able to play the game without encountering system-related issues.

In case you face challenges post-implementation, consider adjusting the boot order in BIOS or seeking further guidance. While it's regrettable that Windows 11 mandates these prerequisites, following these steps should facilitate a seamless gaming experience without resorting to Windows 10 downgrades.

Refer to your specific motherboard or BIOS documentation for precise instructions, as menu layouts and terminology may vary.
