Do you use the latest trainer with the latest/updated game version?
Could you reproduce the issue by what options you have enabled and which might cause the crash you encounter?
This is happening with or without the trainer, I've completely reinstalled the game multiple times to test this. With mods, without mods, with trainer, fresh install using the trainer, and its still randomly crashing even on a install where I never used the trainer.
I am thinking something is broken since the new updates have thrown the game off its rocker a little.
I only activated the trailer. no options enabled.
Game crash when joining the battlefield from the campaign map.
No mods enabled,
