AI Masking not working

I'm having a similar problem on my MacBook M1. Did the most recent LR update a day or two ago. Working on some old files. Got everything working on some files from an event in 2012 but similar files from 2011 have a problem. I want to go to develop and click masking, then select background to darken it. 2012 image: 

2011 image:

The AI select subject button in the 2011 image looks a bit darker than the button i the 2012 image, as if it's greyed out. Also, the 2012 image shows people selected while the 2011 image does not. Clicking on the 2011 button does nothing, while clicking on the 2012 button selects the subject normally. Both images are NEF files, from a D3 in 2011 and a D4 in 2012. However, there are other D3 NEF files from 2011 that work normally. The non-AI masks work (brush, gradients) and the Objects don't work where the other AI selections don't. Since some files work and some don't, I don't see that the GPU would be the problem because it's happening in the same session.

Other files before 2012 are spotty. Some work, some don't. Can't see a common denominator. Most everything 2012 et seq works (too many to inspect all of them, but didn't notice anything until I got to 2011).

Open for suggestions.
