There is way too much focus on the CVR here. There would be no "smoking gun" to point at. Of course they didn't catch the NOTAM, we know that.
The CVR would contain the usual descent check and brief, some chit-chat, I've got the airport in sight, call it? Yeah sure. Whats with the runway lights? yeah it looks like somethings on it? should I ask? yeah? WTH? lets go-around.
