Loading images has become very slow

Windows 10 Pro 16299.309 (latest)

32 GB

i7-6850

GTX-980 graphics with latest driver

Lightroom Classic CC 7.2, Camera Raw 10.2

Samsung 860Evo SSD with lots of room

I work with very large images, typically 470 MB TIFs from a medium format camera.  LR has always dealt with these reasonably quickly, taking about 10 sec to load an image and calculate a histogram.  Suddenly, it has slowed right down.  It is more than minute before the image is available and the histogram shows.  Most of these images have not been worked on and do not have anything in the history.

Nothing on my system has changed.  I have checked the monitor calibration file (fine), tried creating a new catalog, made sure previews are set to auto and 2560 )(correct native res), uninstalled and reinstalled LR, made sure Windows Defender excludes my CR cache, enabled and disabled graphics coprocessing.  Nothing seems to help. LR is till taking forever to load images.

    OK, issue resolved.  I ran a drive test on the Samsung SSD and found the data transfer speed was way down.  Replaced the SATA cable, cold booted, killed a chicken and mumbled.  Not sure which of those worked but the drive is back up to speed and so is LR.

    I suggest trying the simplest fix first, which is to close all applications, shut down your system OS. Restart the system, reopen LR and PS, and try it again.

    If you've already done that try resetting LR's Preferences file. Close LR and rename it by adding .OLD to the name or move it to the desktop. This will allow easily restoring it if of no help. Restart LR and do not make changes to the Preferences settings. Try importing the file again.

    Preferences done as suggested, and made no difference.  Here's a strange one.  LR appears as a running app in task manager.  Then I select an image and LR disappers from task manager.  Keeps running mind you, just not listed as a running app.  I have no idea if that is relevant.
