unsupported mac device + apple logo

Hello,
I have successfully installed macOS Monterey and it's functioning well. However, I'm encountering an issue with iCloud. It's displaying the message: "UNSUPPORTED MAC DEVICE." I'm wondering if anyone has a solution for this. I've already changed the serial number, and it's listed under the "About This Mac" section.

I also have another question. Since iCloud wasn't working, I attempted to use VMware to install macOS. However, I'm unable to get macOS installed as all ISO files get stuck at the Apple logo without a progress bar.

My PC:
- Windows 11 Pro
- AMD Ryzen 7, 5800X
- MPG B550 Gaming carbon (wifi)
- Virtual box version 7 and VMWare version 17.
- 16GB Ram

Can somebody help?
