Issues with Camera Raw recognizing people in the photo.

I’ve been using the “Select People” feature in Camera Raw since it was introduced, and it’s always worked well for me until recently. Now it has completely stopped working.

Every time I try to use it, it processes for a moment and then returns the error: “Unable to select people in this photo.” This happens on every image I try, even simple headshots with a single person clearly facing the camera.

I’ve already tried updating Photoshop and Camera Raw, uninstalling and reinstalling both, and updating my operating system. None of that has fixed the issue. I’ve also confirmed that all other masking tools (object, background, sky, etc.) are working as expected. It’s only “Select People” that fails.

For reference, I’m running Adobe Photoshop v27.5.0 on a 2020 iMac (3.6 GHz 10-core Intel Core i9).

This is a feature I rely on regularly, so it’s been incredibly frustrating to lose it without any clear reason.

Has anyone else run into this issue or found a fix?
