I recently started using lutris for starCitizen and gave this a quick try (run exe inside wine prefix) on a SC app, it runs super good, I tested intro and initial conversation with sister. Only thing that happens sometime is that dialog buttons stay disabled and you cant leave dialog (I assume the issue is me clicking too fast??), but it did not crash on me.
So I assume, the issue is your wine version in lutris or plugins that need to be installed.
Maybe try preparing for SC (just setup, no neeed to install and download actual game)
BTW I have only experience with offline version (v13 current), if you are using online, I have no plans trying that.
