Generate Lightmap UVs .. taking for ever ....

I have looked at all the questions under this … I think.
But there does not seem to be a solution.
I have been letting this run for over an hour now and this is a very low poly model.
Almost entirely boxes.

What is up with this???
… also, is anyone from Unity looking at this board anymore???..

Danger Will Robinson Danger … User Error User Error …

I had two office chairs I had purchased in there with insane polygon counts.
Jeeeeezzzz what a rookie move.

Generate Lightmap UVs seems to be working now …
