I noticed you opened a another thread concerning your laptop APU Processor Ryzen 5800H which means you can't install Ryzen Master in your laptop. It is incompatible with Laptop APU processors only with Desktop APU processors.
That is why it doesn't recognize your processor since it is considered to be incompatible.
Now there is a Lite Ryzen Master that is made for laptop if interested. It is call Ryzen Controller from Gitlabs and Githubs.
Here is the link to install Ryzen Controller from Gitlabs: https://gitlab.com/ryzen-controller-team/ryzen-controller
That should be able to monitor your Ryzen 5800H processor.
You can download a free Uninstaller called Wise Uninstaller. Do a Force uninstall by directing it to the folder or file that wasn't deleted from Ryzen Master and see if it removes all traces of Ryzen Master from your laptop.
Just remember make sure the file or folder is related to Ryzen Master and not to your AMD VGA Driver/program
