The get_saved tracebacks reported in #35263 and #38128 are the same except for line numbers. The more recent, from 3 days ago on Mac.
Exception in Tkinter callback
Traceback (most recent call last):
File "/Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/tkinter/__init__.py", line 1883, in __call__

AttributeError: 'NoneType' object has no attribute 'get_saved'
None.filename from a day ago is also the same except for line numbers. pyshell line 1008 is in PyShell(OutputWindow(EditorWindow)) so get_saved must result from closing Shell. pyshell line 309 is in PyShellEditorWindow(EditorWindow) so must come from closing an editor window.
