copy/pasting ring tones to my Windows desktop with Itunes

iOS & iPadOS

I have been fighting with ITunes for a few hours now. A few months ago, I was able to add newly created ring tones to my desktop and then add them to my media library to complete adding my ring tones to my phone. I just upgraded to the latest version of ITunes, and I am stumped. I can see the list of ring tones I've created, but I simply can not select, copy and paste them to my desk top. Really stuck here. What am I missing?
