Barnes & Noble key can't be retrieved

I recently had to re-install Calibre and all of its plugins to my computer. After adding DeDRM, I tried to retrieve my Barnes & Noble Nook Key, and cannot do so. While I've tried to research this and found this article https://www.aricrenzo.gq/2019-12-13-...r-Nook-Ebooks/ I'm afraid I got completely lost in the weeds.

Is there any way to force a key retrieval for BN books right now?
