I had the exact same problem with Ubuntu (Testing) und Fedora these
days. I had some timers with "OnBootSec=0Min".

And when I started such a timer they crashed the dbus user session.  I
found it out after moving .config/systemd/user to something else,
rebooting and then moving and starting services and timers one by one.
I hope that helps.
