It’s a crash that occurs in versions of OP4 before steampipe, but still steam versions.
The gcf is corrupted.
You need to play on the steampipe version, and if you don’t want to, go for a WON version (basically no steam)
There’s also another solution : Use steam’s gearbox folder, put it in NGHL, then use Yalter’s BunnyXT to remove the speed cap.
