Has anyone got lspdfr working on Linux using Linux apps

It is possible but its a pain in the butt. Here are some helpful steps from a convo with someone else on the areas we got stuck on.

Ok, so far my steps are SPECIFICALLY USE Proton GE 9-27

1. .NET says it's already installed when it isn't

This can be caused by registry keys that need to be removed. From the Protontricks GUI, select "Run regedit" and click OK. Inside regedit, navigate to:
HKEY_LOCAL_MACHINE\Software\Wow6432Node\Microsoft
Once there, delete the "NET Framework Setup" key and all subkeys, and try to install .NET again.

Go to /compatdata/271590/pfx/drive_c/Program Files/Rockstar Games/Launcher/ and follow the guide's instructions from the start. Don't run --no-runtime on the Launcher.exe, otherwise if it breaks you can't kill the process at all. It will fuck plasma and stop GTA V from launching. I specifically used the LSPDFR Setup.exe just to avoid any issues. RPH would not launch for me unless I ran it through

protontricks-launch --appid 271590 --no-bwrap --no-runtime RAGEPluginHook.exe

Yes seems a lot of work to get this working
