"Uh-oh! Lightroom CC needs to be restarted. You've deleted your catalog."
(see screenshot below)
I left LRCC open during the night and was greeted by this error message when I logged back in today.
I obviously did not delete anything.
Fortunately, my catalog was not deleted and all my photos appear to be still in my catalog.
My catalog is stored locally on my Macbook Pro's internal drive, so this is not a case of an external or network drive being temporarily disconnected or anything like that...
I am available to help in providing log files or additional debug info. Just contact me through here asap.
