Following upgrade to LrC 9.3 I cannot create and play a slideshow. It just hangs and some photos in the strip disappear and are replaced with exclamation marks. Eventually it crashes and sends adobe error report. I have reinstalled several times. Following the first reinstall it worked once and then failed again with same results. When I reinstall previous version it works fine. I have a macbook pro ios Mojave.
Thanks Carlos, I have tried resetting the preferences and it enables me to create and play one slideshow before hanging and not playing, then failing to find images. I can see the image in preview pane when manually forward but not in main screen. Same happens when I return to the library mode, images just show and exclamation mark. If I reinstall the previous version it works fine.
