Old world has been crashing ever since 1.17.30 (not fixed with 1.27.32).

My old world crashes after 90 seconds or less of playtime, and cannot be saved after that point.  If I play it will crash after 90 seconds. If I sleep, it will crash upon waking up. If I try to save after doing something or moving to another location, it will crash. If I try to take down signs to remove entities, and then save, it will crash. Size of the world is ~356 MB. Started new world that does not experience this issue.
