Hi,
Thank you for posting the question to the Q&A forum.
Skype for Business 2019 is not supported on Windows Server 2022, below you can find the requirements: https://learn.microsoft.com/en-us/skypeforbusiness/plan/system-requirements
After you have the hardware in place, you'll need to the install operating system (OS) that will allow you to install and successfully use Skype for Business Server 2019.
Windows Server 2019
Windows Server 2016
Anything other than the operating systems listed here won't work properly; please don't try it for installs of Skype for Business Server 2019. For example, the Server Core option is not listed and is thus not supported.
I hope the above information can help you.
