Translated:

When you turn on your PC, after entering your login information, plasma-shell simply crashes; has been tried several times. The system launches Krunner, hence the various applications, but not plasma-shell itself. By specification, yesterday updates were made to the entire kde-frameworks

Comment 2 TraceyC 2025-05-28 18:58:54 UTC

Thank you for the bug report. Based on the backtrace this looks like a duplicate of bug 463648. The fix has been merged to Qt 6.9.2. The crash should stop happening on your system when it updates to Qt 6.9.2.

---

Grazie per la segnalazione del bug. Sulla base del backtrace, questo sembra un duplicato di bug 463648. La correzione è stata unita a Qt 6.9.2. L'arresto anomalo dovrebbe smettere di verificarsi sul tuo sistema quando si aggiorna a Qt 6.9.2.
