LR 6 has reverted to an earlier form and catalog
I have been using Lightroom since 2008, currently on LR Classic version 6.14. Am on PC, Windows 10 pro. I have one catalog with over 300,000 images. Had just finished downloading bird photos from flashcard, culled them, and had just renamed the folder. I may have tried to move that subfolder up one spot. Somehow I abruptly reverted to a much older catalog and an earlier LR panel in the Develop module. I cannot find a way to revert to my current LR again.
