After Update ipv4 autoconfig is broken

After a seemingly innocuous update my Ubuntu 22.04.5 LTS system no longer auto-configures ipv4 networking on ethernet or wifi interfaces. Ipv6 works fine and manually configuring ipv4 works fine.

Here is the apt history from the offending update:

libpskc0:amd64 (2.6.7-3build1, 2.6.7-3ubuntu0.1),cups-filters:amd64 (1.28.15-0ubuntu1.3, 1.28.15-0ubuntu1.4), ovmf:amd64 (2022.02-3ubuntu0.22.04.2, 2022.02-3ubuntu0.22.04.3),google-chrome-stable:amd64 (129.0.6668.70-1, 129.0.6668.100-1),ubuntu-advantage-desktop-daemon:amd64 (1.10~22.04.1, 1.10.ubuntu0.22.04.2),libfontembed1:amd64 (1.28.15-0ubuntu1.3, 1.28.15-0ubuntu1.4),cups-filters-core-drivers:amd64 (1.28.15-0ubuntu1.3, 1.28.15-0ubuntu1.4),nodejs:amd64 (20.17.0-1nodesource1, 20.18.0-1nodesource1),cups-browsed:amd64 (1.28.15-0ubuntu1.3, 1.28.15-0ubuntu1.4),brave-browser:amd64 (1.70.119, 1.70.126),code:amd64 (1.93.1-1726079302, 1.94.2-1728494015),kubectl:amd64 (1:494.0.0-0, 1:496.0.0-0),libcupsfilters1:amd64 (1.28.15-0ubuntu1.3, 1.28.15-0ubuntu1.4),ruby-webrick:amd64 (1.7.0-3, 1.7.0-3ubuntu0.1)

I've tried rolling back libpskc0 and nodejs with no effect. The previous version of ovmf is not available in the repo.

Here is a manual configuration that works (/etc/NetworkManager/system-connections/Wired\ connection\ 1.nmconnection):

[connection]id=Wired connection 1uuid=a9d94420-f026-3f3f-bfdd-8142ae130e71type=ethernetautoconnect-priority=-100[ethernet][ipv4]address1=192.168.0.123/24,192.168.0.1dns=8.8.8.8;method=manual[ipv6]addr-gen-mode=stable-privacymethod=auto[proxy]

And an automatic one that doesn't:

[connection]id=Wired connection 1uuid=a9d94420-f026-3f3f-bfdd-8142ae130e71type=ethernetautoconnect-priority=-100[ethernet][ipv4]method=auto[ipv6]addr-gen-mode=stable-privacymethod=auto[proxy]

Here's the result of ifconfig with the non-working automatic config:

Any thoughts on what could have caused this? How to fix?I don't mind manually configuring my wired connection, but this is a laptop and doing that for every new wifi connection will be a serious hassle.

Thanks for any help.
