docker-mac-net-connect stopped working with 4.16.1

[waterson]

I've had great success running docker-mac-net-connect with Docker Desktop 4.15 and below on an M1 mac.

However, that environment started to get a bit unstable after I upgraded to Ventura 13.1, possibly because of https://github.com/docker/for-mac/issues/6530. Anyway, I recently upgraded to 4.16.1 in hopes of having things get a bit more stable, but I'm not able to get docker-mac-net-connect working anymore. Below is what I see in the debug log...

For now, I've downgraded back to 4.14.1 and things are working again (albeit with some instability):

Thanks in advance for any advice!
