I have all cards from Curse of Naxxramas and nothing.

And why do you think you should get one? There is none.

Yes, this is a known issue, mentioned in the “Known Issues” topic:

[Added 4/5]: The team is aware that the Diamond Loatheb card—a reward for owning a complete Curse of Naxxramas collection—is not claimable by players who already owned the entire Curse of Naxxramas set prior to this patch going live. The team is working on resolving this issue.

Just adding to the list; I also have the same problem. Have the full Naxx set, never dusted any. Have not received Diamond Loatheb and the achievement “Soldiers of the Cold Dark” that has this as a reward already shows as being claimed on 11/12/2020.
