Solution process:

The guest operating system is Windows 11, and the laptop supports TPM2.0 According to the above official support document operation, after opening TPM2.0. Check the secure boot status through the msinfo32 command, but it still shows that it is not enabled. Riot Vanguard cannot run normally. So I changed the customer’s operating system to Windows 10 and closed VBS, so I could run the game normally.

Summary:

  1. If your operating system is Windows 11, please turn on TPM2.0, use UEFI to boot, and check the secure boot status through the msinfo32 command. If it is already turned on, you can play the game normally.
  2. If your operating system is Windows 10, please close VBS directly, uninstall Riot Vanguard and re-enter the game test.
