No, because we had completely re-installed the Adobe Suite when the problem came up and the préférences should be all new.
It also concerns the other apps : Photoshop, Illustrator.. they often collapse after a short while.
This makes me wonder whether another installed Application is bugging the Adobe software. This forum has occasional references to specific softwares that conflict with Adobe Creative Cloud, although a specific one does not come to mind.
I hope that when you reinstalled, you first ran the Adobe Creative Cloud cleaner tool to find leftover bits and remove them?
