💫 What's new

Fixed compatibility with Ubuntu/Debian
‼️ To ensure the launcher works correctly on these distributions, protontricks must be installed using a new method. See the updated Protontricks installation section for these distributions in the README.
Removed the trigger on exit code 1, as it was misleading for most users.
Fake Steam is now automatically enabled if the game was downloaded from FreeTP.
The log now shows not only Wine messages but also the game's own output.
Disabled the ability to enable MangoHud until further fixes are implemented.
Steam is now launched directly via /usr/bin/steam instead of xdg-open (avoids issues on Fedora 42).
The behavior of Fake Steam has been changed — previously, it didn't always restore the Steam PID value in the registry, which caused games to break after applying FreeTP fixes.

▶️ To run, make the installer file executable.

chmod +x onlinefix_launcher_installer && ./onlinefix_launcher_installer

📦 The launcher requires mandatory additional dependencies. See here.
