Heroic had the same problem for me, I think it’s because it installs the latest Rockstar Launcher.

I’m actually using Bottles. What I needed is the Rockstar Launcher installer that is patched and hosted by Lutris. This one:

Oh wow, I downloaded that old patched version (Standalone-1.0.36.344) looking at the install script and it seems to be working correctly!

I guess when I tried installing it from Lutris it automatically used the other method, which downloads the latest version of the Rockstar Launcher that seems to be broken.

Now I need to wait about 2 hours to see if GTAV works correctly, but this is awesome, thank you very much!
