Generalizing this topic to various game titles. Left 4 Dead 2 has already been triaged.
It appears to be an issue with the glibc update https://gitlab.archlinux.org/archlinux/packaging/packages/glibc/-/issues/19
It appears to be an issue with the glibc update https://gitlab.archlinux.org/archlinux/packaging/packages/glibc/-/issues/19
If it is that, this might also be related: https://archlinux.org/news/glibc-241-corrupting-discord-installation/
Also can confirm, and at least from the glibc thread, does not sound like they are interested in doing anything upstream:
https://sourceware.org/bugzilla/show_bug.cgi?id=32653
note: only have been trying CS Source and it has this issue, too.
Latest systemd update broke something and it can't be ran with glibc 2.40 So... Valve, pls fix
Can you guys test again if today's update has fixed the affected Source 1 games?
Different error now for me on CS:S, but it still tries to launch but just dies instantly:

@bakgwailo using "Legacy runtime 1.0" in "Compatibility" settings fixes the issue.
That new issue is probably https://github.com/ValveSoftware/Source-1-Games/issues/7010
@Nyvyme and @Tiagoquix yup, that was it. Works fine now w/ Legacy Runtime
In distributions that ship very recent changes from the glibc 2.41 branch, it will be possible to work around this class of issue in any remaining unfixed games by setting Launch Options to:
GLIBC_TUNABLES=glibc.rtld.execstack=2 %command%
At the time I write this, Arch Linux doesn't seem to have the necessary glibc change yet [edit: it was added later, see https://github.com/ValveSoftware/Source-1-Games/issues/6982#issuecomment-2871965686 ]. This workaround will not be effective until glibc has been updated.
Debian sid since 2.41-7 does have the necessary change, which hopefully means the Debian 13 stable release will also have that workaround available.
GLIBC_TUNABLES=glibc.rtld.execstack=2 %command%
Thanks! This also made Slice & Dice work again.
Not a source game, but maybe other people will find this when they search for the issue.
At the time I write this, Arch Linux doesn't seem to have the necessary glibc change yet, but will presumably pick it up in a future glibc update.
According to https://repology.org/project/glibc/versions this is now in at least: Arch (and relatives like Artix and Manjaro), Debian 13 prereleases (and relatives like Devuan and Kali), Fedora 42, Gentoo, OpenMandriva, Ubuntu 25.04.
It does not seem to be available in at least PLD Linux and Solus, if I'm reading their change history correctly. For various other distributions, I couldn't tell.
I would suggest that distributions that have updated to glibc 2.41 should pick up this change from upstream git for best results. glibc does not do micro-version bug fix releases (2.41.1), so distributions that want to receive post-release fixes need to monitor the release/2.41/master git branch.
This also made Slice & Dice work again.
Please report this to that game's developer - it's good that GLIBC_TUNABLES=glibc.rtld.execstack=2 is available as a workaround, but it would be better if individual games were fixed to not need workarounds (like Valve has done for everything mentioned in this issue, except for Portal 1 which is not fixed yet). Ideally they should recompile with -Wl,-z,noexecstack as described in https://github.com/ValveSoftware/Source-1-Games/issues/6978#issuecomment-2633738175.

They did. They updated Portal 1 to 20th anniversary branch which fixed this issue but it caused crashes and some other issues that they had to revert the changes.
For Portal 1, this seems to have been fixed in the 2025-05-28 update, https://store.steampowered.com/news/app/400?updates=true&emclan=103582791430075523&emgid=520840848816997084. As per https://github.com/ValveSoftware/Source-1-Games/issues/6982#issuecomment-2676164791 I think that was the last remaining Valve game that was known to need fixing? If so, this can now be closed.
If non-Valve games are affected by a similar issue, please report it to the other game's developers, not here - Valve does not control other developers' games (even if they are using the Source Engine too).
For users, https://github.com/ValveSoftware/Source-1-Games/issues/6982#issuecomment-2800172077 is a workaround that should work in many cases.
For game developers, https://github.com/ValveSoftware/Source-1-Games/issues/6978#issuecomment-2633738175 outlines how to fix this "properly". Editing engine.so with execstack -c might work as a stopgap solution in some cases.
