Describe the bug
The program crashes after selecting a game.
To Reproduce
Steps to reproduce the behavior:

1. Run command protontricks
2. Window opens as normal; select game
3. Program outputs the following, then crashes.

~$ protontricks
protontricks (WARNING): Steam library folder /media/disk/SteamLibrary not found. Protontricks might not have access to the directory.

Executing cd /usr/bin
winetricks GUI enabled, using zenity 3.44.2
------------------------------------------------------
warning: Unknown file arch of /home/jbaron/.cache/protontricks/proton/GE-Proton9-11/bin/wineserver.

System:

• Distro: [Mint 22 Cinnamon]
• Protontricks installation method: pipx
• Protontricks version: protontricks (1.13.0)
• Steam version: Standard

I've tried running protontricks with the --no-bwrap command, as I've seen others with similar problems suggesting the same, but the program refuses to run when the --no-bwrap command is added, and simply outputs a list of possible commands as if I had input an invalid command.

Try installing Winetricks manually using the developer's instructions here:

https://github.com/Winetricks/winetricks?tab=readme-ov-file#manual-install

Alternatively, you can install Protontricks from Flathub which comes with its own Winetricks installation.

The problem here is that Winetricks provided by Ubuntu (and by extension any forks like Linux Mint) has an additional patch to make the "Unknown file arch" warning into an error that stops execution entirely, even if the issue is completely harmless. This patch has been removed as of Ubuntu 25.04, but anything based on Ubuntu 24.04 still ships with that patch in place.
