happy New Year to you too as well and I did some research for you and an "empty plugin" is (in a complicated way) when the .esm file points to a .bsa file, .bsa files won't show in mods because they are reskins and textures, for example you may see the High texture resolution packs to have that eye with the line over it saying "empty plugin" and it sounds bad and dangerous and all but all it is is really just mods that reskin that (for some reason) show up on LOOT and overall it is of no danger to you at all, the reason why your game is crashing may be from another reason but empty plugins are nothing to worry about :)
