Docker 4.39.0 slow network performance

After updating from Docker Desktop 4.37.2 to 4.39.0, my containers have experienced slow network performance. I use it to run Vapor Swift apps inside containers based on the Ubuntu 20.04 image, and the initial swift package resolve command now takes about 200 seconds instead of 10 seconds. Downgrading to 4.37.2 restores the original speed.

I’m running macOS 14.5 on an M1 Pro.
