I'm pleased to announce that after allowing the Windows 11, v. 222H2 update to instal on my Beelink AMD that my Windows all-in-one keyboard and trackpad works as expected. It's likely that my Beelink did not ship with all required drivers and that for some reason a direct instal of the keyboard driver was not sufficient. Initially my system reported that there were no further updates, although 222H2 was released on February 28, 2023.
The case was one where stepping away for a few days and allowing the automatic updates to do their work led to a resolution.
Thanks again,
