Launch Issues with Proton

[cloud303-cholden]

I am trying to launch the game, but the launcher is failing to find TaleWorlds.Library.dll and is giving me an error (link). I double checked and the file does exist at /bin/Win64_Shipping_Client/TaleWorlds.Library.dll. I've tried a few variations, but I'm guessing my STEAM_COMPAT_CLIENT_INSTALL_PATH is wrong. Any ideas what might be causing this? Below is my launch script.

STEAM_COMPAT_CLIENT_INSTALL_PATH="$HOME/.local/share/Steam/ubuntu12_32/" \
STEAM_COMPAT_DATA_PATH="$HOME/.local/share/Steam/steamapps/compatdata/261550" \
  "$HOME/.local/share/Steam/steamapps/common/Proton - Experimental/proton" \
    run \
      "$HOME/.local/share/Steam/steamapps/common/Mount & Blade II Bannerlord/bin/Win64_Shipping_Client/Bannerlord.BLSE.Launcher.exe"

The "$HOME/.local/share/Steam" value for STEAM_COMPAT_CLIENT_INSTALL_PATH seems to work for other people, so maybe that's not the issue.

I am also using Proton, although I get the error message popping up as a window: "Failed to find the necessary game files" running through protontricks-launch. May I ask if you installed any extra dlls via protontricks or similar?

You can just use protontricks-launch --appid 261550 path/to/exe
