My question is much like the issue described here, except I'm using an LXC of Ubuntu 23.04. In that answer, it was marked as solved because I guess the networkd-dispatcher service was patched. However, I am getting the same errors in 23.04, and the only way I can stop them is by restarting the service. Here is the journal output of the networkd-dispatcher service showing the error in question:

Is this the same bug reported in v22, but just not updated in 23, or is there some other solution?
