Hi,
This is because if the PC passes the other requirements like TPM and Secure boot, Windows 11 can be installed without a problem, with a disclaimer that updates might be stopped. That being said, your issue of not getting update is different.
Let us try upgrading to 24H2, the latest feature update.
Download Windows 11

Use the Installation Assistant to Download Windows 11

Alternatively, download an ISO file and Run Setup.exe to Start the Upgrade, using Windows 11 Media Creation Tool.
