Unexpected error opening catalog - Windows 10

[BAS_Art]

This occured a few months ago and again today. I tried rebooting my computer and that did not work. My backup was a few days old, so restoring will not help. I have Windows 10, Build 18363. 

What is causing this problem? Can it be prevented? Is there a solution?

Thanks!

I have Lightroom version: 6.14 [ 1149743 ] (I think it's CC 6) does your answer above still stands?

Thanks!
