Just re-start the Mac.
As others have said, it's not clear what you mean by " export … to the cloud." By "cloud" o you mean iCloud, or some other "cloud" service? There is no function in Photos to export to iCloud, so this is confusing.
If this is iCloud, then that being full will cause all kinds of troubles. As Matti Haveri said, if your Desktop folder is in your iCloud drive folder, then you're going around in circles. You should probably disconnect from iCloud before doing anything else. However, if your Desktop folder is in iCloud Drive, you will need to copy those files to a local folder on our Mac. That may be difficult if you don't have enough free space in iCloud for it to function properly.
