since yesterday one of my layouts is not working anymore. I worked on it through the day, saved and closed it and opened it again later. Then the problem appeared. In the preview on the left it just shows a white page, but if you click on the page all elements and timelines are still there. If you open it in the Browser, the elements are shown, but all of the animations don’t work anymore and the layout is messed up.
