Hello. I have created many scenes with many sources for each scene. For example, in one scene, I have audio, image slide show, and video capture. When I first put everything into OBS it worked fine. A day or two later, I opened up the OBS app to find that every source worked except the image slide shows and images that I put up. It is listed that they are still present, but the page is completely black. I use hotkeys for the image slide shows. The only hot keys I used was left for back, right for forward, and space for pause/play. I also put the image slide show on loop. Will someone please help with this problem. I do not know why this is happening.
