Images and videos are not uploading, and page cannot be saved

I've been working on a Divi page for a while now, and all of a sudden, no images or videos are being uploaded. I keep getting errors that say, "Post-processing of the image likely failed because of the server..." for images as well as "Unexpected response from the server. The file may have been uploaded successfully." In addition, whenever I try to save my changes, I keep getting the "Your save has failed" error message. I'm not sure why this is happening because it never has in the past. I've also made sure that the videos and images I'm uploading are all within the size requirements. Please let me know what I could try to remedy this issue. If it helps, we use an AWS server as well as Cloudflare.
