Hello @skroute, your issue sounds like #7813, but the distro-modified Steam package is redirecting some of the terminal spew with key hints that would have helped you find that. Were you checking the "Remember password" box while testing?
The Steam client beta should have some fixes that might resolve your issue. You can try manually opting into the beta client with something like echo "publicbeta" > ~/.steam/steam/package/beta or reset the Steam client once again and select it from the Beta participation section of Steam's settings. Alternatively, you could give https://github.com/ValveSoftware/steam-for-linux/issues/7813#issuecomment-861475454 a try.
Same error for me (Ubuntu 20.04, fresh install with apt works for the first time, login, save password, everything fine, close client, start client, steam exits without errors after STEAM_RUNTIME_HEAVY: ./steam-runtime-heavy).
I tried to disable the network and Steam starts and it works without problem in offline mode, so it seems related to to the automatic login attempt.
I tried the beta client as @kisak-valve suggested and it works like a charm.
That's right, it looks like the client is working as intended when the "Remember password" is not ticked. Symptoms make it look like a duplicate of #7813 .
Thank you for the workaround and quick turnaround, I'll be using it until the fix make it to stable release.
Kind regards
