Would suggest you to go to Lightroom Preferences > File handling > increase the camera raw cache size to 80-90GB > relaunch Lightroom and then, check.
That did it, thank you.
A little premature...That did it for about 5 minutes. Increased camera raw cache to 90GB. Still having same problem.
I have several versions of LR on my computer, LR4 and 5.7.. Should I delete those versions?
I kept 5.7 when 6.3 came out and there were problems with 6.3, I went back to 5.7. Then updated to 6.4 and then 6.5 when the trouble started. Any suggestions.
You can delete the older versions if you no longer need them.
And in Lightroom 6.5, go to Lightroom Preferences > Performance > uncheck "use graphics processor" and then, check.

I could not even uncheck "use graphics processor" before it locked up. Tried again and clicked "Learn more" followed that to:
GPU troubleshooting and FAQ..then to:
Download and installed solutions and problems solved.
Thanks for pointing my in the right direction.
