Yeah, I was running High Sierra and encountered the error where it would launch, but if I made it smaller screen it would crash. I then tried the OpenGL script and it worked once but not after that*.
Since then, it crashes immediately on attempted launch if I try a default launch, or does the windowless launch with the OpenGL – the OpenGL bar can’t even be dragged around, because it’s not visible.
I had updated to Mojave to attempt to fix this – no luck, same problems. Just to add, this started pre-latest patch (after the big one though), and uninstalling / reinstalling game doesn’t fix it.
*I used a prepackaged version of the script from this user – I’m wondering if there was something else in there that could have inadvertently messed it up, as it’s much longer than the script in your first post. Maybe you could take a look if don’t mind?
