RAW images open in Lightroom, Elements and Photoshop with artifacts

When I open RAW files in Lightroom, Elements and Photoshop, images open in Develop module with rows of red and black pixels throughout the image and blocks of random colors.  I uninstalled/reinstalled Lightroom and installed a new graphics card with no improvement.  JPEG files open correctly.   This problem also occurs with Elements and Photoshop.  If I open a RAW files in Luminar and export it to Lightroom, the problems disappears.  I tried changing settings in Lightroom, to no avail.  This problems began with Camera RAW 12.3 and continues with 12.4.  I also converted RAW files to DNG and the same problem occurs.  This problem is present with RAW files from various camera formats, Olympus, Nikon and Sony.
