Unable to upload media

Is anybody else having trouble uploading media today? I've done everything I can think of and still I get just gray boxes where my photo media should be. I've duplicated the file, restarted, deleted and reuploaded, and gone through all the steps over and over but nothing works. I'm on version 6.1.0.587.7 Creative Cloud and I'm using Safari 17.4.1

Help! Thanks.
