Thanks for your posting on Q&A.
As far as I know, we could get the hotfixes of windows server 2022 by selecting the following Products and Classifications.
Product: Microsoft Server operating system-21H2
Classification: Security Updates
Please try to tick the above products and classification and sync on the WSUS server. Then we could confirm whether we could get the hotfixes.
Hope the above will be helpful.
