events list in the dashboard are gone

the events are listed fine on the main homepage, in the backend where you go to see the list of events they are ogne, they have disappeared. I did a time zone reset which did not help. Divi is up to date. no other plugins have been added. I’ve had no issues for years, this must have happened in the last couple of weeks. I was able to edit current events by going outside the dashboard and clicking edit. thank you.
