Camera Raw v15.0.0.1264

Hi, everyone -- hope you can help me. Since Photoshop just updated, my RAW files don't open automatically into Camera RAW. Also, when using Geometry in CR, there's no option to constrain crop. Last, in Optics, there's no option to do automatic adjustments (vignetting and distortion) or chromatic aberation. Did I change a setting or something? I'm using Windows 10. Thanks in advance.
