Yup. You just closed it manually:

No im serious i didn't even touched it

Thats what it says

@Gabriel1, are you aware that when you load the map editor the game will load all of the mod files in your mod folder, and that it loads them in alphabetical order? Do you really need all of those mods to do map editing? As Zniwek said,

I also see many warnings in your game log which are not related to ProMods 2.11.

That looks like the map editor aborted loading, not a crash. But I agree that the error you listed is responsible for the abort. Again, I am sure it has something to do with other mods besides ProMods (or your ProMods definition file is corrupted).
