Z790 on Sequoia - can't sleep or shutdown

Hello,

I have installed a fresh copy of Sequioa 15.0 on my z790 PC and I can't get it to sleep or shutdown/restart.
When attempting to enter sleep the monitor and peripherals turn off but the computer stays awake.
When trying to shutdown it freezes the display and I have to force shutdown.
I have mapped USB ports, checked for other device sleep issues but cannot find the root cause.
I've also tried to change SMBIOS from iMacPro1,1 to MacPro7,1
no luck so far.

My hardware:
Asrock Z790M-ITX WIFI
Intel Core i7-13700KF
AMD Radeon RX 6800 XT

EFI Folder is here

this is my Opencore boot debug log

Any advice will be helpful!!!
