May you please provide more details?

This is different of what I saw before:

When splitting python blocks in an org file I got a long list of warnings: Warning (org-element): ‘org-element-at-point’ cannot be used in non-Org buffer #<buffer *Org Src rpasyncio.org[ python ]*> (python-mode)
until it stopped by itself.

I traced this to user-errors in my own `org-babel-edit-prep:python' which I
use to let eglot handle python source blocks.

I rewrote my `org-babel-edit-prep:python' to get rid of user-errors but
then I bumped on the user-error coming from `org-src--make-source-overlay'.

I think that this may be the case for other definitions of `org-babel-edit-prep:LANG'

I copy my `org-babel-edit-edit-prep:python' without user-errors below:

#+begin_src emacs-lisp -n :results silent
(with-eval-after-load 'emacs
  (defcustom eglot-maybe-ensure-modes '(python-mode)
    "Modes where maybe `eglot-ensure' should be or has been called.
This may be in the case of proper directory local variables or in
the case of proper `org-src-mode' buffers.")
