I was using Roboviz without any problems on macOS Monterey after the upgrade to macOS Ventura. The simulator window doesn't appear. There's no error in the terminal too.
This is a known problem. I guess, it's probably due to some changes in version 3 of Metal. However, I'm not aware of any workarounds to make RoboViz run on macOS Ventura.
