Previews not showing, Photos won't export

[dblivewire21]

Out of nowhere, my pictuers wont export. They will stay on this screen.

Also, my previews will not show (after I've already looked at them and did my editing.) A similar thing happened on my Lightroom Classic which is why I switched to Cloud. What is happening? I need answers quick. I've done multiple restarts and closing of the app.

The 'CLoud' icon has a red dot! Does this suggest your are not online?
