For me, this looks like either a mixed installation (please post the output of M-x org-version) or some third-party package misbehaving.
M-x org-version says: Org mode version 9.5.3 (release_9.5.3-511-g8e69ad @ /usr/local/src/org-mode/lisp/)
Can you try to open that file from emacs -Q? See https://orgmode.org/manual/Feedback.html
It's not just that file, it's been happening recently with almost all my Org files, now and then. I'll try with -Q and work on a file for a while and see if I can recreate the problem.
Is there anything from all your excellent folding work that would let me check some value or variable that would be helpful when I see such a problem? Some way of inspecting the state of something that might be useful?
