Does not launch through Proton on Linux

[Qunas101]

I just want to leave this issue here in case someone who has more experience with Proton is able to find a solution.

First of all, you need to put %command%/../SFR.exe in launch options - note how the slashes are reversed compared to the usual way. Then when you try to launch the game you will be presented with a choice, if you choose 1. SFR, then another terminal window called "Wine Debugger" will briefly open and that's it. That's how far I got. If you choose option 2. SFD then vanilla sfd will launch with no issues.

Tested with Proton5.0-10, GE-Proton8-14, GE-Proton8-25. Also installed dotnet45 with winetricks as required for vanilla sfd

A screenshot of the terminal, maybe that could be a lead. (I'm only seeing the exception on GE-Proton8-14 though)
