I'm having the same thing happen, and it seems to crash while loading maps from games like GTFO (The menus load fine, the game and Steam crash when loading a map. The game and the client also have a low chance of crashing when doing alt+tab in games like Risk of Rain 2.

Good news, I figured out what caused the crash. I was running Steam off the terminal to read the output, and I got Steam to crash, but the terminal also crashed. Something was wrong beyond Steam.
My first instinct was OOM killing the thread because it used too much memory. I consulted Journald and I was right!
I disabled OOM with the command systemctl disable --now systemd-oomd.service, and it works fine!

This is a ridiculously bad idea. You system might crash in a bad way.
Nothing extracted yet.
