Using Obok when importing from Kobo

- Calibre 7.1 + DeDRM/Obok 10.0.3
- Calibre 7.1 + DeDRM/Obok 10.0.9
- Calibre 6.29 + DeDRM/Obok 10.0.3

Every failure produced the same error.
Source is a book bought off of Kobo Website, and I'm extracting it from the desktop app "Kobo Desktop".
Since this log doesn't really show anything, what happens when you click the Obok button? Does it not find your Kobo library? Kobo Desktop is on the same computer and user as calibre/DeDRM?
@ElleKayEm When I click the Obok button, it's able to show my Kobo library without issue, the book I'm attempting to import shows there're no DRM for some reason with an unlocked green padlock symbol. After importing, I'm unable to properly view the book within Calibre, images are missing and gibberish text.
I've seen other people report that happening. Books that do have DRM showing as not so they just get imported as is without Obok even trying to remove the DRM. I've very rarely seen it myself, but closing and reopening Kobo Desktop and calibre resolved it for me. Books then show up with red closed locks (if applicable) and get decrypted properly when added. Some people have said they don't have trouble if they close Kobo Desktop before trying to import. Others still have the issue.
Thanks, seems like the restart worked. Will close this now.
Glad that worked for you! And thanks for reporting back. This was with calibre 7.1 and Obok 10.0.9?
