I found an old Reddit Thread where another User was also trying to get Ryzen Master to work in Windows Server 2019 but was unsuccessful.
He tried a Hack or fix from Github but then when installing Ryzen Master he kept getting errors concerning that it was the wrong Windows version.
Since you are using a Windows Server OS, try posting your question at AMD Server Gurus. Maybe someone there can suggest a different program that you can use to monitor your processor's parameters or to change them if necessary from here: https://community.amd.com/t5/server-gurus/ct-p/amd-server-gurus
You can also open a thread at Github and see if anyone has been able to install Ryzen Master since they did post a fix or hack to get it to install and work in the past.
If not you can also open a AMD SUPPORT ticket and ask them from here: https://www.amd.com/en/support/contact-email-form
NOTE: Some Users have been having problems posting at Server Gurus. So if your post doesn't show up within 24 hours notify the Moderator to see what happened. Seems like some posts goes into the SPAM folder and it isn't posted.
EDIT: Tagged a Staff member from AMD Server Gurus to look at this thread @ozzymesa
