Since nvidia 535.x and new Steam GUI windows might not spawn and you have trouble using it. Here are ways to solve this:

$ steam -vgui launches Steam with partly old UI. Should work, but can’t use friends network and if opening game properties webview will crash and reset.

$ steam --reset redownloads the steam runtime. Need to relogin. At least some Preferences are lost (compatibility / Proton for games, Settings like GPU acceleration). The new UI might launch though, at least until you restart your PC or restart steam. (https://wiki.archlinux.org/title/Steam/Troubleshooting#Steam_window_does_not_show_on_Nvidia_GPUs_after_the_June_14,_2023_update)

(Edit: This worked just once)

$ __GL_THREADED_OPTIMIZATIONS=0 steam There should be almost no downside to this, prob some small performance loss. Source: https://forums.developer.nvidia.com/t/steam-for-linux-client-not-showing-ui-with-535-43-02-245/256178/9

In this thread this also was mentioned:

$ steam -no-cef-sandbox but this sounds unsafe. I suggest this only as the very last resort.

If you found a working solution, you can make an alias, e. g.: alias steam='steam -vgui'

Alternatively, just install the flatpak. Since the flatpak package brings it’s own runtime packages, it just works.

    You most likely do not have the correct lib32-nvidia-utils installed. They pushed nvidia-utils 535 first while lib32-nvidia-utils 535 was stuck in testing. This basically caused Steam to not load up properly.

    If your lib32-nvidia-utils isn’t the correct version, you do not need to do any of these steps. Simply update it to resolve this issue.

      When I upgraded lib32-nvidia-utils was already at 535, and the problem itself is still there for me. The probable cause is libcef invalid opcodes (dmesg)

    I also had problems today with Steam but with a different solution. I had to remove the xdg-desktop-portal-gnome to get any window to show up for Steam

    The -vgui option hasn’t worked for me unfortunately. I ended up downgrading to an older steam version for now and that got me going

      Yeah flatpak packages bring their own runtime packages so they’re more independent of the underlying system. I installed the steam flatpak now and it works just fine
