Since some time now the Steam Flatpak cannot start up and I have no idea why this happens.

Web research leads to basically nothing that is related to what I experience so I assume it has something to do with my system. Other Flatpaks start up normally and I can use them.

When resetting everything related to the Steam Flatpak and reinstalling it from Flathub it loads and installs the Flatpak and then installs all necessary stuff

[various update-related stuff]

steam.sh[2]: Steam client's requirements are satisfied

So everything looks good up to this point. The small Steam update windows poppend up several times indicating the running installation/update. The output then continues:

(The last line gets printed twice, yes.)

The first startup process then hangs there for a few seconds and continues with this.

After the command prompt is shown agein, this gets printed:

At the given location there is no dump file.

Do you guys have any Idea why this happens and how I can fix it?

    Okay… Now that you have the non flatpak steam, could you remove flatpak and xdg-desktop-portal*?

    Reboot and launch steam again.

    This is the last idea I have for now… If this also doesn’t help, it is probably a different issue than this and this, and you should report it to valve.

      Thanks for all your help with this. Unfortunately Steam still scrashes. The xdg-pdesktop-portal packages aren’t installed. Only the Flatpak package seems to have them as hard dependency.

      Valve said they won’t give any support here because I’m not using Ubuntu with Gnome.

      So no more Steam games for me, I guess …

        This just can’t be…

        After some deep digging, I found one last Idea. Try launching steam with the -vgui flag and let me know if that works.

          This just can’t be…

          Yep. This makes no sense at all. But I have no idea what to try anymore.

          Try launching steam with the -vgui flag

          Unfortunately this does not change the behavior. It still does the same thing as described before.

            Well that’s that then. I also have no idea what to try anymore… I guess you’ll just have to wait until some random update fixes the issue. Sorry.

            Edit: Since you reinstalled everything, I think it could be some cache on your system that went bad. That would explain why both the Flatpak and native versions don’t work and why the rest of your system works. But I have no idea where that cache might be…
