You seem to have a custom compatibility tool for Steam that has a weird compatibilitytool.vdf file that Protontricks can't parse correctly. It could be broken for some reason, or a valid VDF that Protontricks can't parse yet.

Since you've installed Protontricks from AUR, could you try running the following command:

$ python -m pdb -c continue /usr/bin/protontricks --gui

When the crash occurs, enter command locals(), which should print a list of variables related to the VDF file that was being parsed. You can then copy the output into a reply.

For example, here's an example of the command-line session where I've deliberately modified the VDF file for SteamTinkerLaunch to cause a similar error (compatibilitytools changed to scompatibilitytools):

@Matoking here is myoutput:

It seems all my compatibilitytool.vdf file is empty

[Matoking]

Thanks, I've pushed a fix to master that should ignore empty compatibility tool manifest files since the Steam client also does the same thing. Since you're on Arch, you can install protontricks-git from AUR to get the fix working immediately.

Do you have any idea what might have caused the compatibilitytool.vdf files to become empty? I checked GE-Proton 7.55 myself and it has a valid compatibility tool manifest, so I'm guessing some third party tool might have emptied the file for some reason?
