Could you share a bit more details? What version of Lightroom are you using? Also, please check if there are any driver updates for your GPU. Sometimes the tool might not detect people, especially if there are many elements in the photo. Try cropping out any distracting elements and see if the people are detected correctly.
Thanks! Alek

Hi @Aleke , This is the Version of my Lightroom (please see the attached photo), even I cropped the photo it's still the same. I'm using RTX 4070 updated version and studio driver from nvidia.
