ConditionPathExists=/ostree was not met, Could not activate remote peer 'org.projectatomic.rpmostree1'

After Kinoite upgrades to 40 yesterday, all rpm-ostree commands return an
error: Loading sysroot: Failed to invoke RegisterClient: GDBus.Error:org.freedesktop.DBus.Error.NameHasNoOwner: Could not activate remote peer 'org.projectatomic.rpmostree1': unit failed.

When I check systemctl status rpm-ostreed, it says

systemctl start rpm-ostreed has no effects.

Update: seems working fine now.
