The currently packaged evolution also appears to suffer from other
issues (see e.g. https://issues.guix.gnu.org/62942)  You may want to
try that patch or wait for it to be upstreamed.

As a matter of principle, don't install Guix from old ISOs.  Instead,
use `guix time-machine' or inferiors with Scheme.

None of this is useful.  For accurate version information, use `guix
describe'.

IIUC the fix to that one is to install evolution-data-server in the
operating-system packages rather than on the user level.  Since
evolution is tied to its data-server, you'd need to have both in the
operating-system (my personal fix is to extend the gnome package so as
to include them both, but that's besides the point).  Since evolution
launches for you, this bug doesn't seem apply, however.
