And looks like my Nvidia driver, both on computer and used by flatpak Steam is NVIDIA 550.90.07
Thinks it's same as this error https://github.com/ValveSoftware/steam-for-linux/issues/11006
If you are using the unofficial Flatpak version of Steam as provided by Flathub, then this is probably https://bugs.launchpad.net/ubuntu/+source/apparmor/+bug/2072811, an Ubuntu/AppArmor regression. Valve cannot fix this, it's something for Ubuntu to solve. Logs for this version of Steam end up in ~/.local/share/flatpak/com.valvesoftware.Steam/.local/share/Steam/logs instead of the usual ~/.steam/steam/logs.
If you are using the unofficial Snap version of Steam as provided by Canonical, then please report issues to https://github.com/canonical/steam-snap/issues. Logs for this version of Steam end up in ~/snap/steam/common/.steam/steam/logs instead of the usual ~/.steam/steam/logs.
I think you must be using one or the other of those, because if you were using a system-wide .deb installation, then ~/.steam/steam/logs would have existed.
To fix this, you need to start Linux in KMS mode. On Nvidia, adding the kernel parameter 'nvidia_drm.modeset=1' would do it. On AMD/other cards, probably some other kernel parameter.

That can't be it. I'm already doing that.

In other words, 'sudo cat /sys/module/nvidia_drm/parameters/modeset' responds with 'Y'?
KMS fixed webhelper crashing for me, I can run it gpu accelerated and with cef sandbox. Had I known it was a DRM issue, I would have done it earlier. Another thing that has had DRM issues is Wayland, which you said you were using. Try it with Xorg?
I also have the nvidia modules (nvidia nvidia_modeset nvidia_uvm nvidia_drm) baked in to the initramfs. Shouldn't make a difference unless your rig loads nouveau instead.
Yes, sudo cat /sys/module/nvidia_drm/parameters/modeset returns Y for me. I also have the exact same issue in the Plasma X11 session. Every first launch of Steam after every boot will result in "steamwebhelper, a critical Steam component, is not responding". Every subsequent launch will succeed.

Reminder that "steamwebhelper, a critical Steam component, is not responding" is a symptom, not a root cause. @TheLiberaceSequence and @Fell are not necessarily seeing this message for the same reason that @RichardJECooke did, and are not necessarily even seeing this message for the same reason as each other.
Linux distributions are complicated things, so there are lots of reasons why steamwebhelper might crash or not work, and any of those reasons will result in you seeing basically the same symptom.
Steam developers are unlikely to be able to solve issues like this one without logs from the affected systems (see https://github.com/ValveSoftware/steam-for-linux/issues/11088#issuecomment-2228900423 for where to find those logs).
My issue was resolved when Ubuntu released an emergency rollback patch of their apparmor change. So we can probably close this issue for a new one.
I had the same issue.
It turned out that in my attempt to reducing the size of data coped between two systems when upgrading, I had omitted copying all sorts of cache files, profile wise, i.e. every directory named "cache" or similar and their contents.
I had figured that cache files would be generated anew. But it seems that Steam doesn't attempt to recreate missing directories.
I get similar errors in webhelper-linux.txt and my client starts ok and I can launch games, but
can not access the steam overlay.
A reinstall using https://steamcommunity.com/sharedfiles/filedetails/?id=2307584451 fixed my overlay problem. It also fixed a problem on another machine with symptoms similar to this ticket. My guess is the steam upgrades are sometimes broken and it is best to reinstall.
I'm experiencing this issue as well

When opening Steam today it should open but it doesn't. It says
steamwebhelper, a critical Steam component, is not responding. I tried all the options to restart. Same error. Restarted computer. Same error. Updated all flatpaks, snaps, and debs. Same error.What else can I try to fix this please? I don't want to reinstall my entire library and lose all settings in non-cloud games.
