Very nice detective work.  Thank you.

Yep, I can reproduce it on my end.

The culprit is a8e812e60 (org.el: Restore the scroll position after
cycling, 2020-09-05).  However, at the time of that commit, the change
didn't trigger the hang with the default Org settings.  However, once
that commit was merged to master (5beeb094a), it started to trigger it
with the standard Org settings because the default value of
org-startup-folded changed to showeverything (88f5ed91c).

Anyway, this is fixed (on my end, at least) by 4f8ac0a7a.
