I need to turn on the secure boot to play valorant. The bios is UEFI, the disk where the windows installed is GPT, CSM was disabled booted before enabling secure boot. Did try the custom and standard secure boot to no avail.

Every time i boot it with the secure boot on, it black screened. The pc is on and so does the keyboard. The keyboard is responsive and i could do restart from ctrl alt del shortcut. And every time I restart it, the pc booted to BIOS menu without anything done to the keyboard. Disabling secure boot returns the pc to boot as normal. With or without enabling CSM.

What would be the issue here? Please help me fix it this.
