Protonhax in launch options line causes games not to launch

[Krythulu]

Evening,

I install Protonhax and I attempted to launch GRAND THEFT AUTO V with the launch properties line protonhax init %COMMAND%. However whenever I launch the game, it doesn't do anything. It just says "launching" then it stops.

Steps to reproduce

1. Git clone Protonhax
2. Add executable perms
3. Add protonhax to path
4. Change launch perms to protonhax init %COMMAND%

I even attempted to launch Core Keeper with the same command line but it doesn't work. Any tips would be appreciated

OS: Linux Mint 21 Steam Version: Native

Hope this gets patched
