Auctex not loading in Emacs 27.1 from Homebrew on MacOS

[Benedikt Nordhoff]

Hi,

homebrew updated my Emacs to 27.1 today and now auctex 12.2.0 fails to load with the following error. 

Debugger entered--Lisp error: (wrong-type-argument stringp (require . info))

  string-match("\\(\\`\\|/\\)desktop\\(\\.elc\\|\\.el\\|\\.so\\)?\\(\\.gz\\)?\\'" (require . info))

I’m on MacOS 10.13.6. The same error also prohibits me from using the TeX-submit-bug-report command.
