Not sure if that is a actual crash though because I do notice the taskbar does disappear but when explorer.exe really crashes or even when you restart the process, it will always not show all the system tray icons unless you manually restart the processes either by restarting or killing and then starting them manually. For all we know, it could be a resource leak from certain apps that is causing it. Just like MSMoneyquotes.exe works fine for me in Windows 10 but in Windows 11, the process will eventually die on it's own when it feels like it, hard to say if it's the app itself or if it's windows killing it.
