I have installed a patch (so far only on savannah, but not on GNU
Elpa).  Can you please try it out?

Actually, the patch has two pieces:

- an embarassing piece fixing an old bug not directly related to your
  problem

- a second piece that should fix your problem.  This piece is a little
  annoying:

  BBDB now uses `gnus-info-params' that was a macro up to Emacs 26;
  it was turned into a function starting with Emacs 27.  Then, when compiling
  BBDB, it makes a difference whether the compiler expands the macro in
  old versions of emacs, or whether it calls the function that exists in
  newer versions of emacs.  So compiled code for BBDB works only for the
  older or newer version of Emacs for which it got compiled.



  ;; If BBDB was compiled with an old version of Emacs up to Emacs 26,
  ;; this will fail if the code is loaded into a newer version of Emacs.
