A recent update to the Creative Cloud desktop application introduced a defect which can cause the Adobe folder in the Preferences folder to not have proper user permissions. When the CC applications attempt to access this folder, and are unable to write to it, they crash. Engineering is aware of this issue and is working to address it. In the meantime, manually fixing the permissions on the Adobe folder allows the applications to launch correctly.
