Secure Boot variables are locked after enrolling keys with sbsigntools

Hello! I tried to make my own SB keys using sbsigntools, after enrolling the keys, it did not work, so I tried reverting the keys in the UEFI, but I got errors when trying to do that:

"Secure Variable Update is locked down"
"Try again after System reboot"

and

"Delete Security Key/Database"
"Security Violation"

I've already tried to reset the UEFI & take out the CMOS battery, nothing changed. I am using a Aorus Z390 Pro WiFi on Arch Linux with GRUB.
