I am finding @ScarlettSh0‘s English perfectly understandable. If you are having difficulties understanding another forum member’s post, it would be better to politely ask the person to rephrase his/her post.
As for the crash, @ScarlettSh0 is correct about its cause. One of your mods implemented a custom config parser, which caused the crash because its config has errors. The best solution would be to delete the config folder, or delete each config one-by-one until the config causing the problem is removed and regenerated by the game.
