where do i find subject selection on camera raw 16.1.1

Perhaps a camera raw preference reset will solve the issue:

• Hold down the Command key and select Photoshop > Preferences > Camera Raw (macOS) or hold down the Ctrl key and select Edit > Preferences > Camera Raw (Windows).

• Click Yes in the dialog that asks "Delete the Camera Raw Preferences?"
