Catalina shutdown problem

Hi I installed the latest version of macOS on my system. Whatever I did, I couldn't fix the system shutdown problem. Help me please.
I downloaded Catalina from the app store.I installed usb with Unibeast.
Then I set my bios settings and installed macos. With Multibeast, Uefi BOOT mode AppleALC, Realtek RTL8111 v2.2.2, USBInjectAll option, I introduced ethernet, sound, and my video card recognizes native.
I installed the system successfully. But system shutdown does not work
Help me please
