dont work after last update of the game

is there any detail of that? i upgraded to factorio version 0.18 lately. Chose the version that occurs before the update (fpp version 0.17.x). Show me any detail of this, an error message or something.

I am playing version 18.4 with the most recent version of FPP I can find. The message I get when trying to load the game with FPP active is this (sorry for any minor mistakes, the text is quite small, minor details may be off slightly):

Error Loading mods

Mods to be disabled:
*FPP

Update: This happens regardless of whether I run the game with other mods or not.

that is the exact same log i get

finally, i got my time for bugfixing the mod. but i could not reproduce the crash. usually, that happens on new beta branches of factorio. if the crash still remain, may i ask one of you for contact data?
