Why does VirtualBox keep launching on boot?

Sorry if this kind of question isn't allowed here, but I'm at my wit's end. VB randomly started launching on startup about 2 weeks ago (on EndeavourOS) and I can't figure out why. There's no shortcut in ~/config/autostart, it isn't in the KDE startup apps list, and I can't find anything virtualbox-related with systemctl either. There's also no setting in the VB app itself. WTF?
