Stable 9.5: invalid function (date date)

[Jarmo Hurri]

Greetings.

I just installed (stable) 9.5. from GNU ELPA, and tried to see what my
agenda for today looks like. The agenda is empty, and I got error

Debugger entered--Lisp error: (invalid-function (date date))

with backtrace

  (date date)()
  org-agenda-get-day-entries("/home/jarmo/projects/gtd/faq.org" (10 2 2021) 
:deadline :scheduled :timestamp :sexp)
  apply(org-agenda-get-day-entries "/home/jarmo/projects/gtd/faq.org" (10 2 
2021) (:deadline :scheduled :timestamp :sexp))
  org-agenda-list(nil)
  funcall-interactively(org-agenda-list nil)
  call-interactively(org-agenda-list)
  org-agenda(nil)
  funcall-interactively(org-agenda nil)
  call-interactively(org-agenda nil nil)
  command-execute(org-agenda)

Any ideas?

I am running

(emacs-version)
"GNU Emacs 27.2 (build 1, x86_64-redhat-linux-gnu, GTK+ Version 3.24.30, cairo 
version 1.17.4)

Have fun and stay safe.
