Same for me, the upgrade went horribly also wrong...
But i could get everything on track again from the terminal with a complete update and upgrade the missing packages.
Did not have to do install systemd-resolved as i already had the latest installed.
Then in Ubuntu 24 desktop i had troubles with long minutes hanging on a grey screen, firefox freeze at start up and other desktop freezes..
A snap store refresh did the job with 'sudo snap refresh snap-store' and everything is working fine now !
