Steam

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?
