`org-element-at-point` cannot be used in non-Org buffer

[braudelan]

After recent upgrade of my doom emacs this bug shows up when calling org-agenda. Similar to /alphapapa/org-web-tools/issues/56 and /nim-lang/nim-mode/issues/246.

Stacktrace:

Same here.
Latest Doom on Emacs29 on Mac OSX.
Org-agenda and org-journal are now broken because of stricter mode enforcement in 'org-element-at-point'.
(EDIT: Actual change causing this seems to be org-parser now rejecting non-org buffers..)
