@JohnFromGWN I used the 600+ cars gameconfig that I usually install, and then I get that error. Although after a few failed attempts with that, I replaced it with another gameconfig that came out about a week ago. That actually launched the game, but it still crashed with the same error about 10-15 mins later.

I have the most up-to-date gameconfig from the site, running my game off of a Gigabyte laptop, and have it installed on a separate drive from main.
First time I've had a problem with this.
