Interestingly, it looks very similar to 10 years old BUG 343976 and BUG 344799 Unfortunately, after updating Qt, Bridge and Frameworks, issue still persists.

bit tired of seeing Proton Mail Bridge crash every time when exiting, so I asked ChatGPT for help analyzing the gdb backtrace, due to my incompetence with C++/Qt. To keep things short, ChatGPT determined that the culprit of the crash is Proton Mail Bridge itself. Though I still don't understand why it doesn't crash under a COSMIC session, as I reported in https://bugs.kde.org/show_bug.cgi?id=500563. Anyway, after a little back and forth, ChatGPT suggested me to add this code in Proton Mail Bridge's QMLBackend::init() [1]: // make sure the tray icon is destroyed before QApplication dtor connect(qApp, &QCoreApplication::aboutToQuit, this, [this] { trayIcon_.reset(); }); So I added that after line 67, rebuilt and repackeged the Proton Mail Bridge, and sure enough, it stopped crashing after exiting! I'd send a pull request to Proton Mail Bridge, but I don't feel confident enough to send PRs for stuff I didn't come up myself. But if anyone reading this wants to do that, please go ahead. It'd be great if KStatusNotifierItem could prevent this crash somehow, but I have no clue if that's even possible.
