To ensure games run well on Linux either via Native Linux builds or Windows games with Proton, part of the magic is in the Steam Linux Runtime. A new version of it, the Steam Linux Runtime 4.0 was recently put up with some pretty big changes.

What's the point of it? It ensures Steam and games run through Steam on Linux work properly across all the many different Linux distributions. Another secret Valve sauce for Linux. Well, not secret at all but you get my meaning I'm sure.

I'd suggest trying to launch the flatpak from the terminal and seeing if there's any strange logging.

Already did that but I couldn't see anything that I could recognize as abnormal. The "Connecting" window shows up, actually. But it just stops loading for a second and then it just says "Reaping pid" in the console and it closes the process.
