My (unsupported) desktop PC is an AMD Ryzen 7 2700 eight-core CPU running at 3.2Ghz with 16GB of RAM and 2TB of SSD storage. It handles Windows 10 Professional but is apparently incapable of running Windows 11. I don't have a Webcam, but maybe face ID login is now mandated? It will be something stupid like that. I have no interest in replacing this machine though.

The missing requirement might be no TPM 2.0

It's more likely you have TPM disabled—there's no webcam requirement, and Zen+ is supported.
