I am using the latest Calibre version, but suddenly the downloaded metadata does not show in the book or in the main interface.
After download I click on the path. I see the opf file but when I click on it, I get the message ERROR: loading book failed
When I click on show details I get the below message
Spoiler:
"calibre, version 5.31.1
ERROR: Loading book failed: Failed to open the book at C:\Users\Meher_shroff\Documents\00 Mamaijee Data Files\Calibre\Emma Cole\The Complete Dark Duet_ Lark and Nig (18)\metadata.opf. Click "Show details" for more info.

None of the above makes sense to me but I copied and pasted as someone at help desk will make sense of it.
All along I was easily able to download metadata, and embed it in the book. Pls where is my mistake now?
Thank u
