I have been working in after effects for awhile now but all of a sudden, the preview will not load. The preview box is blank and any thumbnail for any video in my bin is black. Everything works except the previews and I have rendered it out and the video is perfectly fine. I have tried rendering it, opening the file in a new project, checking the visibility of all the clips, and wireframe is off.
Start by flushing your caches and reset the workspace.
