What caused the crash

I added a submenu to the system tray based off of https://github.com/AlephNought0/Faeryshell/blob/master/bar/left/Submenu.qml
It crashes after running for a bit, while periodically printing this:

ERROR quickshell.incubator: Destroyed incubation controller QObject(0x7efd6ebfeac0) is not known to EngineGeneration(0x7efd6ea89040) , this may cause memory corruption
ERROR quickshell.incubator: Current registered incuabation controllers QList(0x7efd6ebdfb50, 0x7efd6ebdfb50, [many more addresses])

Minidump

Managed to accidentally delete it, but it was still in my terminal scrollback so here is (most of) the file.

Can't manage to trigger this one myself, and it's likely somewhere in the QML engine.
