Please describe your issue in as much detail as possible:

The Steam client is crashing on startup. I see the following errors when I try to run it from the terminal:

/usr/share/themes/Gnome-Prof-dark/gtk-2.0/main.rc:733: error: unexpected identifier 'direction', expected character '}'
/usr/share/themes/Gnome-Prof-dark/gtk-2.0/hacks.rc:28: error: invalid string constant "normal_entry", expected valid string constant

Steps for reproducing this issue:

  1. Run steam

  • Opted into Steam client beta?: No (not that I am aware of)
  • GPU: NVIDIA GeForce RTX 3070
    Error:

/usr/share/themes/Yaru-dark/gtk-2.0/main.rc:775: error: unexpected identifier 'direction', expected character '}'
/usr/share/themes/Yaru-dark/gtk-2.0/hacks.rc:28: error: invalid string constant "normal_entry", expected valid string constant

Edit to add:
Reinstalling steam seems to have addressed the problem

@neilsimon Hi! It seems the issue was local for me. I checked the steam crash dump and saw that it was somehow using stale versions of the nvidia drivers (470), even though my system already has the newer version (580).
from dump:
ee0fe000-ee102000 r-xp 00000000 103:07 1968008 /usr/lib/i386-linux-gnu/libnvidia-tls.so.470.161.03

Have you updated the nvidia drivers recently? If so just check and remove the old driver files
find /usr/lib -iname "*nvidia"
When I delete old libs, steam runs ok.

Nothing extracted yet.
