Error occurred while exporting file

Hi,
I have this error message when I try to export some files from DAZ Studio. I don’t have this problem every time, sometimes it works and sometimes it don’t. For a while I have this error more frequently and I don’t know how to solve it. Does anyone have any idea on how this error can be fixed? Why I have this error message? Thank you!
