Konqueror opens with multiple "save as" dialogs open

When I launch konqueror (either from console or shortcut, simply using konqueror command), it opens, but then immediately opens two "save as" dialogs (both targeting the downloads dir with a filename of "blank"). If I try to actually click save rather than cancel, another popup appears saying Unable to create io-slave, Unknown protocol 'konq'. I have no idea (a) what's making the save dialogs appear or (b) what they're trying to save (though I suspect the former Q is the only one that matters). My Konqueror is Version 22.12.0, I'm using KDE Plasma 5.26.4 on a distro of Debian specific to my employer.
