[BUG] org-element--cache: Org parser error [9.6 (release_9.6-90-gf49ee9 @ /home/stefan/.emacs.d/contrib/org-mode/lisp/)]

[Stefan]

Hello everyone,

I recently upgraded to Org 9.6 via Git (and to Emacs 28 with nativecomp), and 
since then I get this kind of warnings all the time. They appear at different 
spots in my org files and there is nothing special with the headings in 
question.

This specific warning appears when I load the standard =a= agenda:
