After updating MacBook Air to Ventura cannot connect to 802.1x secured wifi (eduroam). Any solutions?

After updating my MacBook Air to Ventura macOS 13.0 I cannot connect to 802.1x secured wifi (eduroam).

Any solutions?

I tried the recommendations in this post from moons0n.

deleted eduroam profile (accepted new one) + reboot
deleted eduroam from Keychain + reboot
deleted the .plist files from Library/System + reboot, I found these and moved them to a folder on the desktop:

NetworkInterfaces-pre-migration-new-target.plist
NetworkInterfaces-pre-migration-source.plist
NetworkInterfaces-pre-repair.plist
NetworkInterfaces-pre-upgrade-new-target.plist
NetworkInterfaces-pre-upgrade-source.plist
NetworkInterfaces.plist
preferences-pre-migration-new-target.plist
preferences-pre-migration-source.plist
preferences-pre-repair.plist
preferences-pre-upgrade-new-target.plist
preferences-pre-upgrade-source.plist
preferences.plist
preferences.plist.old

Whatever I try, I do not get a working ip-address, always a 169.etc address.

The same eduroam-login works fine on the iPhone next to the MacBook.

Other wifi networks also work fine.

Interestingly, under System Settings > Wifi > Details > 802.1X it says

Authenticated via EAP-PEAP (MSCHAPv2)

in spite of the self-assigned ip-address.
