I see you said upstream that https://invent.kde.org/qt/qt/qtbase/-/commit/c956eb8eddb1b3608d7e3d332fbe55df5ec41578 was supposed to fix it, and that got cherry-picked to 6.7.0, but unfortunately we have duplicate reports with the same backtrace from people using Qt 6.7.0, 6.7.1, and 6.7.2. Re-opening.
