i also find out guys, that the file from cloud are not editable, it is possible that all my smart object has been gone?
Try downloading your file from the cloud and then try linking it to your object.
I loathe Creative Cloud. If one of our other operators accidentally has an embedded creative cloud object in their photoshop file, it causes nothing but problems. How to find a file, which should be on the system but has been seconded into the creative cloud. Especially if that operator is sick or on leave.
