This is caused by https://bugs.launchpad.net/juju/+bug/1897743 where the upgrade-charm hook is not run on 2.8.4 causing the venv to not be rebuilt to pick up any changed wheelhouse entries (in this case, a new dependency in the snap layer).

A workaround is to manually run the upgrade-charm hook on failing applications:

juju run --application etcd -- hooks/upgrade-charm

This was fixed in Juju 2.8.6.
