Yes thanks for the heads-up about the update being released, I installed it too and the security issue warning has gone so seems fine now.
By the way the driver blocklist on/off toggle might still be greyed out and stuck On but that is by design now as if you have Memory Integrity (aka HVCI), Smart App Control, or S mode enabled then the Driver Blocklist is forced On as it is part of those functions. If you disable those then the toggle becomes active and Driver Blocklist can now be switched on or off as you wish.
