For anyone coming across this in the future. After reading some on the steam-for-linux github issues (https://github.com/ValveSoftware/steam-for-linux/issues)
From this…
I opted into the steam beta thru the client (had to run steam --reset) about 5 times before I could get it to run. I also came across a suggestion to remove xdg-desk-portal-gnome.
After that, steam seems to be working for the time being!
