I recently switched the hackintosh from clover to opencore. It is almost prefect, but having a wake up and shutdown/poweroff issue. Once I shutdown the machine, it will go to a black screen, with the machine still on. I guess the black screen is saying that the machine closed the os already, but the machine is still running (leds on and need to force pressing boot button to poweroff the machine).
After the shutdown problem, it comes with an wakeup problem. It wakes and go to safe mode in the bios, need to press f1 and go to bios and then reboot, after that it boot like normal. I just found this wake up problem may be solved by DisableRtcChecksum. (https://dortania.github.io/OpenCore-Post-Install/misc/rtc.html#finding-our-bad-rtc-region) The wake up problem seems to be solved, but the shutdown/poweroff problem still exists.
Does any have similar issue? Thank you so much.
My build:
CPU: i9-9900k
Motherboard: Asus z390-h gaming
Graphic: Radeon vii
Opencore 0.7.4 Big Sur 11.5.2
I made my own EFI at the very beginning, but after a lot of trial, I found this similar EFI does the same, so I started from this now:

Please give me some advices. Thank you so much.
