*** EDIT ***
This question is out of date. None of the provided solutions worked for me. In the meanwhile, both Ubuntu and Steam got their updates and everything is working as expected now. If you are here with the same issue, try updating your software.
*** END EDIT ***
I've used the pre-release Ubuntu 22.04 with Steam Play and experienced no issue. Now that I've reinstalled my computer with the official Ubuntu 22.04 release, I cannot get Steam Play to work anymore. Unsupported titles won't run anymore, both with the experimental Proton as with previous versions of Proton.
I get the feeling I'm missing some packages or something but I wouldn't know what since I'm not getting any errors. I wouldn't know where to start with this issue ... any help would be greatly appreciated.
I've installed steam from the .deb file downloaded from steampowered.com
--EDIT-- Following the suggestion, here's the output when I launch a game that's not supported, but used to work in the beta:

at the moment, the only way I can get Steam to work on my amd ubuntu 22.04 is to install it from flatpak.
Oddly, I had the same issue you had and I just added the multiverse repository through the following command and Steam started to detect network and work again:
sudo add-apt-repository multiverse
I did not install any new package after the command above nor the apt update/upgrade pair installed something. Steam just worked after several attempts to run it. May be just coincidence or maybe it fixed something.
1You will solve this by editing the file /usr/share/applications/steam.desktop, on line 38 change "true" to "false", save, restart and try to run.
