        Hi,
if I'm not mistaken, then it means you've written something in:

   $ gsettings get org.gnome.evolution.calendar primary-tasks

which is not a valid source UID reference. It could be in the past, but
it's not anymore. Try to run this in the terminal:

   $ gsettings reset org.gnome.evolution.calendar primary-tasks

eventually set it to the On This Computer/Personal task list:

   $ gsettings get org.gnome.evolution.calendar primary-tasks 'system-task-list'

Looking into the runtime warnings you pasted, there are more affected
places, not only this one. Maybe you might reset all the stored
GSettings, to start from fresh. I've no idea what could happen to it.
You can reset it with (I didn't try the commands):

   $ gsettings reset-recursively org.gnome.evolution
   $ gsettings reset-recursively org.gnome.evolution-data-server

Use it with caution.

That the Evolution crashes with this is a bug, or at least an
unintended behavior. I do not know whether the crash you face is
addressed by the following change, which landed for 3.40.2, but I'd
guess it is:
https://gitlab.gnome.org/GNOME/evolution/-/commit/54829e3a734028a531f6f

        Bye,
