Hi, when I try to run steam it just crashes on "Loading user data". When I run it in a terminal I get this:

The easy solution is to just delete your entire steam installation and run it again.

In reply to @thegreenguy:beeper.com
do you mean to rebuild switch after removing steam from my configuration.nix and then add it again?

In reply to @charles:computer.surgery
but unfortunately, i can't get it to do 240Hz at 7680x2160 over DP 2.1, swaymsg -t get_outputs shows a max of 60Hz at that resolution
