for me and my girlfriend situation is equal. If you click too fast or too slow Mac didn't change language(((( sometimes change sometimes no. The problem is software, Mac is totally new (MacBook air 15 M2)

alex@alex ~ % sw_vers ProductName: macOS ProductVersion: 14.0 BuildVersion: 23A344 For UDP looks like it can send and receive messages. But if I try TCP mode: alex@alex ~ % sudo nc -l 53 nc: Address already in use lsof report for port 53: COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME mDNSRespo 209 _mdnsresponder 54u IPv6 0x374deabe82ef1a55 0t0 UDP *:domain mDNSRespo 209 _mdnsresponder 55u IPv4 0x374deacce7bb82ad 0t0 TCP *:domain (LISTEN) mDNSRespo 209 _mdnsresponder 56u IPv6 0x374deabe73abbd95 0t0 TCP *:domain (LISTEN)

Internet sharing disabled. I took a few extra tests. So looks like if I switch off docker - port 53 is free. So the problem is related to Docker. I shure that other containers not using this port. I found information about a simular issue here: https://github.com/docker/for-mac/issues/5335 People propose to turn off Virtualization Framework feature - but for me it didn't help. Tommorow will try other solutions. If you have ideas what can help pls share them here.

I tried it with my MacBook 15 2018. First I updated docker for the last version. Tried on Mac os Ventura - everything is ok. After that, I updated Mac OS to Sonoma and immediately got this problem. And the worst problem is that now I can't roll back Mac OS to Ventura. It just shows me an error((( I spent 5 hours yesterday. Now both machine (macbook pro 15 2018 and macbook air 15 M2) are on Mac OS Sonoma and is blocking my work with this problem(( when I try to rollback on macbook air 15 m2 it shows me message like this (and something simular with macbook pro 15 2018):
