After yesterday updates my emacs does not start properly

After yesterday’s updates my Emacs can not load the start buffer giving an error message: “Cannot open load file: No such file or directory, auctex/font-latex”. The auctex package is still installed (throug melpa).
The other functions seem to be ok.

I am experiencing the same problem on a current Leap 15.1 Installation.
Is there any way to solve this?
