So the circumstances are pretty easy to recreate, it only crashes when i try to search up the items either by using the search function in creative or clicking on the transportation tab.
Did try to run it without any other mods, still crashed the game.

... As i was posting this, a new version of forge was uploaded, Forge 2765 instead of 2764 that i was using.
It solved the issue.

Sorry.
