I think the relevant error message here is:
[0325/105134.224938:ERROR:directory_reader_posix.cc(42)] opendir /tmp/dumps/attachments/6444653e-e946-4fd0-b1f5-e21f6f1c7298: No such file or directory (2)
This looks a bit like #10549. Check that /tmp/dumps is either owned by your user ID or deleted.
If you are running Steam on a multi-user system, each user will need to delete /tmp/dumps before the other user can run Steam successfully.
I tried both deleting the /tmp/dumps folder and changing the permissions to 777 recursively (it was already owned by my user), and neither option changed the outcome.
This was also one of the things I tried before. (I forgot to list it in the Issue)
This is duplicate of #10577 I think.
The symptom is the same, but there is not enough information available to the public to know whether the root cause is the same. steamwebhelper developers might be able to get more information from any crash dumps that are uploaded (but coming from the Steam Runtime side, I don't have access to those).
Mixing up more than one root cause with similar symptoms in the same issue report tends to lead to long, confusing issue reports where it's never clear whether the issue is fully fixed or not, so it might be better to keep separate issue reports separate.
I recently set up another device with vanilla archlinux and used steam on it without issues for about a week. But now something seems to have changed (I guess there might be some other package at fault, which I installed on the original device and now on the new one) and the same issue appeared there as well.
I looked through my command history and inspected all newly installed packages but there is nothing that stands out.
I don't really have any clue on how to narrow down the source of the issue, if anyone has an idea of how to continue, i'd greatly appreciate a hint.
(I also tried nuking the steam directories on the new system, including common and compatdata as I had only installed a single game anyways, this didn't change anything)
I guess there might be some other package at fault, which I installed on the original device and now on the new one
That sounds plausible to me. In particular, if you have a previously-working system and now it no longer works, that is an excellent starting point for figuring out what the key factor was.

Some ideas:
~/.local/share/Steam/logs, which might have useful information. If the symptom is "Steamwebhelper is not responding" then logs related to steamwebhelper will be particularly relevant. Attaching updated logs here (repeat the command you previously used to create steam-logs.tar.gz) could also help Valve developers to identify the problem, even if there is nothing that stands out to you./var/log/apt/history?)LD_PRELOAD modules, GTK modules, Vulkan layers, anything else involving code injection into another process, or generally anything that could be described as "unofficial" or "weird".Nothing extracted yet.
Your system information
Please describe your issue in as much detail as possible:
Steam worked flawlessly until roughly the start of this month.
Since then, when launching steam (steam-runtime or steam), only the dialog window "Steamwebhelper is not responding" appears. (none of the options in the dialog help)
After reading through a lot of similar Issues I tried deleting ~/.steam and ~/.local/share/Steam (except for the ~/.steam/steam/steamapps/common and ~/.steam/steam/steamapps/compatdata folder) but this did not resolve the problem.
