When i try to Export a Adobe Cloud Library onto any Drive, after some % i get an error message with "something went wrong" and "contact support"

Hey! i want to Export some Libraries that i share with other people of the company to one of our drives to archive it and make space for new ones. When i try to Export the Lib through the Adobe CC desktop app, after some % i get an error message saying “something went wrong” and “contact support”. Its not always the same % and there is plenty of space on the Drive. I even tried other drives and the drive where CC and the temp lib files are located, nothing worked so far. 

Maybe someone had same issues and a solution for this? :)

Thanks in advance!
