There is a much more official and up to date figure:
> We project the cost to fly a single SLS/Orion system through at least Artemis IV to be $4.1 billion per launch at a cadence of approximately one mission per year.

From what I understand, that number does include ground systems.
For what it's worth, NASA leadership continues to contest this value, although they refuse to publicly give their own value.
To be fair to you, the $4.1B figure does not ignore development costs. I don't think there's an agreed upon way to include them, so everyone just mentions them separately. And they are quite... large.
Kind of sad that the last living pieces of the shuttle will be dropped into the ocean and left to rust away
I know a lot of people want to get them into museums, but I suspect that every museum that really wants one already has one. And I'd suggest to you that it's much more dignified that they go out as part of a rocket launch than slowly decaying in a warehouse somewhere.

The ~$5B figure is in the final para. And that still sounds like it excludes ground systems and Orion development costs. (Plus ~4 more years of ever-growing bloat, obviously.)
