Skyrim Missing basic .esm files

[Bladerunner5664]

Hey,

Whenever Im trying to load up a savegame, Skyrim is telling that its missing following .esm/.esp files

skyrim.esm

dragonborn.esm

hearthfires.esm

dawnguard.esm

unofficial skyrim legendary edition patch.esp

skyrim unleashed II.esm

upon loading any savegame it obviously crashes.

I can start a new game without any issues, but I can't load up any savegame.

I'd appreciate any help with this problem.

 

So apparently some mods I had recently installed caused this problem to occur.

I just removed these mods and reinstalled them after starting the game once.

 

But the problem still persists with certain other mods.
