I have installed a fresh copy of Windows 11 from a flash drive, and the problem didn’t persist in the fresh installation. I upgraded the software from 10 to 11 during the early days. Most early Windows 11 birds have faced the problem and those who have upgraded from the earlier version. The VAN9001 error appears on recently upgraded Windows gaming machines.

The anti-cheat system is effective and Riot Games are utilizing the new technology. The game identifies the cheaters in the game and blocks them permanently. I have never seen an anti-cheat system like Vanguard. I play Apex Legends, PUBG, Counter-Strike, Dirty Bomb, etc. Millions tune in to Valorant every day because they have an effective anti-cheat system. You have to enable TPM 2.0 and Secure Boot from BIOS to fix VAN9001. The physical TPM 2.0 prevents privacy invasion, and a secure boot prevents system boot file modification. The TPM 2.0 is a physical chip, and Secure Boot creates unique keys. I have come across Chinese programs selling openly and designed to bypass the lock screen. Microsoft understands the existing security loopholes in the earlier version. Let me give you a few valid reasons why Vanguard stopped Valorant from launching. The error code VAN9001 states that Windows PC couldn’t find enabled TPM 2.0 and Secure Boot in the system. I have shared a snapshot below, and it clearly says, “this build of vanguard requires TPM version 2.0”. Why is Vanguard preventing Valorant to launch? #
