On June 19, evening, I lost all my files in the sidebars. The images are on my computer, but Lightroom, and Photoshop too, can't see them. They came back once, but not again. I have only two folders that I can open.
I can access the photos in Windows and online, but the Lightroom catalogs don't show up any more.
I'm using an HP Envy laptop, Windows 10, Firefox browser.
