I wanted to post this crash workaround if anyone else is having the same frustrating issue. For the demo and now full release the game will run once perfectly on my computer, 2017 iMac running Bootcamp, but will crash with no error every time trying to play after the initial run. I was guessing that there might be an issues with settings or cached files so I started poking around and found if I delete the files in the games TempState directory I can run the game again, but just have to fix my video settings again at startup. I’m not sure which file in the directory is causing this, but the game repopulates the TempState each time so I just remove the folder before starting the game to get it to run again. I always make a copy to the desktop in the event removing it causes any issues, but so far the only issue is having to fix my video settings each time.
