Reopened as got same Message /administrator/components/com_content/Helper/PreviewHelper.php on line 18 again as saving a new Article.
Are you sure, that you are up to date? Because line 18 is not the starting block of the comment in the preview helper class.
I think that Cloud Access Nightly is not containing the patch.
@franz-wohlkoenig You're installing Nightly Builds trough ccp or manually?
It is quite possible that there was an issue at CA and they didn't update the nightly
