Novel has been deleted?

opened my novel and for some reason everything is gone. My chapter titles are still there in draft one and two, the novel title is still there. But when i go into my chapters, everything is gone. No words. even my editing notes and settings, everything is titled but all the words are gone. Empty pages. There is no backup, I did not delete anything. I’ve been using this program for nearly two years and have never had a problem.
Can anyone help? This is devastating. I am heart broken.

Did you move the project? Use a cloud service where you save it?

I have the same issue
