The crash happens somewhere in Tk (see stack trace below), this might be a bug in the Tk library itself. See also #93042.

I can reproduce this issue under Python’s bundled Tcl/Tk 8.6.12. Using LLDB to jump over the [NSApp _resetAutoreleasePool] call removed in Tcl/Tk 8.6.13 (see https://core.tcl-lang.org/tk/info/d638e7ca3616) prevents this issue. So I believe the fix for #92603 also applies to this issue.

Sorry, the crash is still possible in Tk Aqua 8.6.13. The change I mentioned does seem to prevent the crash, but it does not eliminate it completely.

The crash is still possible with Python 3.11.4
