I also tested using Emacs 28.0.60, but on Linux. Can you try exactly
same steps I used for testing?

1. Save the attached file to /tmp/problem.org

2.

mkdir /tmp/orgmode-test
cd /tmp/orgomode-test
git clone git://git.sv.gnu.org/emacs/org-mode.git
cd org-mode/
emacs -Q -L ./lisp -l org /tmp/problem.org

3. M-x org-agenda <RET> < a

If you do not see the heading listed in agenda view after doing above
steps, can you also try to go to org-element.el and change
"(version< emacs-version "28")" in org-element-cache-map to
"(version< emacs-version "29")". Then, try the above steps again.

Best,
Ihor
