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.

(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 (

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
-vguioption hasn’t worked for me unfortunately. I ended up downgrading to an older steam version for now and that got me goingI run the Flatpak version and I do not have any issues regarding this.
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
