Fixed in commit 914c220. Root cause: EnginesPanel._install_pack() runs the SDK install on a background thread and calls wx.CallAfter(self._after_install, message) when it finishes. If the AI Hub is closed before the install completes, that queued callback still fires against an already-destroyed setup_btn, raising this exact RuntimeError.

_after_install now catches RuntimeError from the dead widget and returns cleanly instead of crashing — the install itself already ran (or failed) in the background regardless, there's just no panel left to update. Regression test: tests/unit/ui/test_ai_hub_engines_panel.py.

This is very likely the underlying crash behind your OpenAI configuration report as well (a separate fix, commit 24c0dc6, now correctly detects a crash-interrupted install as "not installed" instead of permanently stuck).
