@Knudsen88 script hook is not causing issues like this, there are 4 options what can be wrong.

You are missing gameconfig or heapadjuster, problem is caused by menyoo (try to delete it) you have installed any other mods which are causing this problem, most probably models ised in that mission you have any other asi files or scripts which are causing this for example vehicle control script is glitching missions even that it's not related to the missions
