Seems like it crashed while trying to print one of these warnings: qt.qpa.wayland: setGrabPopup called with a parent, QtWaylandClient::QWaylandXdgSurface(0x6080002b8a20) which does not match the current topmost grabbing popup, QtWaylandClient::QWaylandXdgSurface(0x608000365da0) According to the xdg-shell protocol, this is not allowed. The wayland QPA plugin is currently handling it by setting the parent to the topmost grabbing popup. Note, however, that this may cause positioning errors and popups closing unxpectedly because xdg-shell mandate that child popups close before parents
Perhaps the KWayland people can help us here.

While on Dolphin, I clicked on the hamburger menu and was navigating the submenus, suddenly, the menu disappeared, but the hamburger button still seemed like it was pressed. I kept moving the mouse and some submenus were still getting triggered. In the terminal, this message was repeated over and over: qt.qpa.wayland: setGrabPopup called with a parent, QtWaylandClient::QWaylandXdgSurface(0x55a143bd5790) which does not match the current topmost grabbing popup, QtWaylandClient::QWaylandXdgSurface(0x55a144b651f0) According to the xdg-shell protocol, this is not allowed. The wayland QPA plugin is currently handling it by setting the parent to the topmost grabbing popup. Note, however, that this may cause positioning errors and popups closing unxpectedly because xdg-shell mandate that child popups close before parents I'm not sure it's a new bug or the same as this one, since it doesn't crash the session. To trigger it, just keep navigating the hamburger menu on Dolphin until it suddenly disappears. I think it might be easier to trigger it with many submenus open in the "More" submenu.
I tested this in Kate and the menu also disappears sometimes just like in Dolphin, but I can't make it crash. It must be the same bug as this one.

Can't reproduce this on Plasma 6, it should be fixed.
