Start by reproducing the macOS Dock New Window sequence described in the issue and inspect the crash entry point UIActionHandler::isValidAction in libbinaryninjaui. Trace the action after a newly created window is closed, then verify that repeatedly creating a window from the Dock menu no longer crashes.
