It's same, there is no backtrace even I toggled debug-on-error to t.

And I also tried you org-element-cache options:

#+begin_src emacs-lisp
(setq org-element--cache-self-verify 'backtrace)
(setq org-element--cache-self-verify-frequency 1)
(setq org-element--cache-diagnostics t)
#+end_src

This does not generate backtrace too.

Now I tried your latest push. The errors gone. But org-agenda entries still missing. I checked
*Messages* buffer, no error messages, including other error special buffers. no information.
