Long shot since the other cogs all shift well.
While I'm thinking of it - maybe there should be a spacer between the hub and cassette that's not there?
I loaded the bike in my truck to go to the co-op. Otherwise, I would check with a different wheel. I likely can do that there if all else fails. It seems unlikely, there is no play in the cassette to speak of and just eyeballing it, nothing looks off.
