Do you have two installations of Steam, one installed using Flatpak and another other than Flatpak? Protontricks found both ~/.steam/root and ~/.var/app/com.valvesoftware.Steam but in this case it should prioritize the Flatpak installation of Steam (i.e. ~/.var/app/com.valvesoftware.Steam) instead of mixing the two installations together, as it has done here and which might explain the crash. I'll prepare a fix for this.

---

If you are intending to use Protontricks Flatpak with the non-Flatpak version of Steam, you could either remove the other Steam installation or use the STEAM_DIR environment variable to explicitly choose the Steam installation. For example, you could use the following command:

STEAM_DIR=$HOME/.steam/steam flatpak run com.github.Matoking.protontricks -v --gui

You could also create aliases to separate the two installations. For example, you could add these to your ~/.bashrc to create two different commands, one for Flatpak and the other for your distro's own Steam installation. This could be handy if you need two installations of Steam:

alias protontricks-flat="flatpak run com.github.Matoking.protontricks"
alias protontricks="STEAM_DIR=$HOME/.steam/steam flatpak run com.github.Matoking.protontricks"

I've pushed a potential fix to the Steam installation discovery. Could you try installing the fix using the following command and check if it fixes the issue?

flatpak install --user https://dl.flathub.org/build-repo/73729/com.github.Matoking.protontricks.flatpakref

STEAM_DIR=$HOME/.steam/steam flatpak run com.github.Matoking.protontricks -v --guiit's worked nicely! No crash and i can see games in my library. Thanks!
flatpak install --user https://dl.flathub.org/build-repo/73729/com.github.Matoking.protontricks.flatpakrefit's not worked. I see again wrong steam installation and its crashes with same error like before.

The Flatpak version of Protontricks defaulting to the Flatpak version of Steam is intentional, but the crash is not.

It seems like that Proton is installed for Flatpak Steam, but hasn't been launched yet, which is causing the crash. Proton versions except for Proton Experimental install a directory named dist the first time that Proton installation is used to launch an app, which Protontricks needs to work properly.

I've pushed another potential fix. Could you try running this command to install the newer fix:

flatpak install --user https://dl.flathub.org/build-repo/73814/com.github.Matoking.protontricks.flatpakref

After that, try running the following command:

$ flatpak run com.github.Matoking.protontricks -v --gui

Assuming everything works correctly, it should now instruct the user to launch a Steam app at least once to ensure that the Proton installation is finished. If not, the problem is probably elsewhere and needs more investigation.

flatpak install --user https://dl.flathub.org/build-repo/73814/com.github.Matoking.protontricks.flatpakref

log changes but still only 2 games and crashes...

Investigated this problem more, and turns out that while both versions of Steam write the identical path ~/.share/local/Steam into their own configuration files, that path corresponds to two different locations depending on which Steam installation is in use. In short, Protontricks was looking for Flatpak Steam's apps in the wrong place.

Third time's the charm, hopefully. Could you try installing this fix:

$ flatpak remove com.github.Matoking.protontricks # Remove the existing installation first
$ flatpak install --user https://dl.flathub.org/build-repo/74209/com.github.Matoking.protontricks.flatpakref

and test the following command again:

$ flatpak run com.github.Matoking.protontricks -v --gui
