My experience as well, except the spinning icon freezes and a crash report is generated, which I complete and send. I will post my system info below:

Hi Stephen,

Have you done some edits on the cr2 file? If yes, can you try reseting all the changes and running Enhance Details again and see if that helps.

Hi Gupta, it's not working either with edited or unedited Raw files for me.

Similar story, long process (7 days) to upgrade to windows 1809), I get intermittently the never ending spinner.  For me it happens on Fuji .RAF files.

The issue is intermittent.  After shutting down LR and restarting, the same image was successfully enhanced detail.

I have same issue with [Enhance Details Preview] shows spinning wheel and "Loading".  No preview is generated.  Confirmed update to Windows 10 version 1809 (OS Build 17763.316).  Tried [Lightroom] > [Preferences] > [Performance] > [Use Graphics Processor] both on and off.  Tried .RAF (Fuji) and .ORF (Olympus) raw images.
