I have a catalog of about 1200 photos that was working for about a week. I had already completed quite a bit of work, editing around 300 photos and rating all 1200. However, each time I open the catalog now, it crashes within 2 minutes of opening after loading correctly with all of my images and work visible. All other catalogs are working fine without any crashes. I have not moved the files for the catalog in question, and the files seem to be fine otherwise. I am very hesitant to make a new catalog and start over since I will probably lose about 15 hours of work. Please let me know if you have any tips.
